Use undo ip pool to remove an address pool or an IP address range of the address pool.
Examples # Configure an address pool aaa that contains IP addresses 129.102.0.1 through 129.102.0.10 for the group a. system-view [Sysname] ip pool aaa 129.102.0.1 129.102.0.10 group a Related commands display ip pool link-protocol ppp Use link-protocol ppp to enable PPP encapsulation on an interface. Syntax link-protocol ppp Default PPP encapsulation is enabled on all interfaces except Ethernet and VLAN interfaces.
pap: Uses PAP authentication. call-in: Authenticates the call-in users only. This keyword can be configured when the local end serves as the receiving end of DDR calls. For more information about DDR, see Layer 2 — WAN Access Configuration Guide. domain isp-name: Specifies the ISP domain name for authentication, a case-insensitive string of 1 to 24 characters. Usage guidelines PPP authentication includes the following categories: • PAP—Two-way handshake authentication. The password used is in plain text.
ppp chap password Use ppp chap password to set the password for CHAP authentication. Use undo ppp chap password to cancel the configuration. Syntax ppp chap password { cipher | simple } password undo ppp chap password Default No password is set. Views Interface view Predefined user roles network-admin Parameters cipher: Sets a ciphertext password. simple: Sets a plaintext password. password: Specifies the password for CHAP authentication. This argument is case sensitive.
Views Interface view Predefined user roles network-admin Parameters username: Username for CHAP authentication, a case-sensitive string of 1 to 80 characters. The username is sent to the peer for the local device to be authenticated. Usage guidelines To pass CHAP authentication, the username/password of one side must be the local username/password on the peer. Examples # Set the username for CHAP authentication to Root on interface Serial 2/0.
If a host is connected to the device through PPP, you can execute the winipcfg command or the ipconfig /all command on the host to check the DNS server IP addresses assigned by the device. Examples # Set the primary and secondary DNS server IP addresses to 100.1.1.1 and 100.1.1.2 for the peer on interface Serial 2/0. system-view [Sysname] interface serial 2/0 [Sysname-Serial2/0] ppp ipcp dns 100.1.1.1 100.1.1.
ppp ipcp dns request Use ppp ipcp dns request to enable a device to actively request its peer for the DNS server IP address through a port. Use undo ppp ipcp dns request to restore the default. Syntax ppp ipcp dns request undo ppp ipcp dns request Default A device does not actively request its peer for the DNS server IP address.
Predefined user roles network-admin Parameters username: Username of the local device for PAP authentication, a case-sensitive string of 1 to 80 characters. cipher: Sets a ciphertext password. simple: Sets a plaintext password. password: Specifies the password for PAP authentication. This argument is case sensitive. If simple is specified, it must be a string of 1 to 255 characters. If cipher is specified, it must be a ciphertext string of 1 to 373 characters.
Usage guidelines In PPP negotiation, if the local device receives no response from the peer during the timeout time after it sends a packet, the local device sends the last packet again. Examples # Set the PPP negotiation timeout time to 5 seconds. system-view [Sysname] interface serial 2/0 [Sysname-Serial2/0] ppp timer negotiate 5 remote address Use remote address to configure an interface to assign an IP address to the client. Use undo remote address to cancel the assigned IP address.
[Sysname-Serial2/0] remote address 10.0.0.1 # Configure Serial 2/0 to assign an IP address from the address pool aaa to the client. system-view [Sysname] interface serial 2/0 [Sysname-Serial2/0] remote address pool aaa Related commands • ip address ppp-negotiate • ip pool timer-hold Use timer-hold to set the interval for sending keepalive packets. Use undo timer-hold to restore the default.
Use undo bandwidth to restore the default. Syntax bandwidth bandwidth-value undo bandwidth Default The expected bandwidth (in kbps) is the interface baud rate divided by 1000. Views VT interface view, MP-group interface view Predefined user roles network-admin Parameters bandwidth-value: Specifies the expected bandwidth in the range of 1 to 400000000 kbps. Usage guidelines The expected bandwidth of an interface affects the link costs in OSPF, OSPFv3, and IS-IS.
This command might fail to restore the default settings for some commands for reasons such as command dependencies or system restrictions. Use the display this command in interface view to identify these commands, and then use their undo forms or follow the command reference to individually restore their default settings. If your restoration attempt still fails, follow the error message instructions to resolve the problem. Examples # Restore the default settings of interface Virtual-Template 10.
display interface mp-group Use display interface mp-group to display information about a specified MP-group interface or all MP-group interfaces.

Packet statistics are not performed for VT interfaces. Brief information on interface(s) under route mode Brief information about Layer 3 interfaces. Link status: Link: ADM - administratively down; Stby - standby • ADM—The interface has been administratively shut down.
Parameters interface mp-group interface-number: Specifies an MP-group interface by its number. If no MP-group interface is specified, this command displays MP information for all MP-group interfaces. Examples # Display MP information. (MP is configured through an MP-group interface.
undo interface mp-group mp-number Default No MP-group interface is created. Views System view Predefined user roles network-admin Parameters mp-number: Specifies a number for the MP-group interface. Usage guidelines The interface mp-group command is used together with the ppp mp mp-group command. You can execute the two commands in any order.
Usage guidelines To remove a VT interface, make sure all the corresponding VA interfaces are removed and the VT interface is not in use. Examples # Create interface Virtual-Template 10. system-view [Sysname] interface virtual-template 10 [Sysname-Virtual-Template10] mtu Use mtu to set the MTU size of an interface. Use undo mtu to restore the default. Syntax mtu size undo mtu Default The MTU size of an interface is 1500 bytes.
ppp mp fragment disable Use ppp mp fragment disable to disable MP fragmentation. Use undo ppp mp fragment disable restore the default. Syntax ppp mp fragment disable undo ppp mp fragment disable Default MP fragmentation is enabled. Views MP-group interface view Predefined user roles network-admin Usage guidelines If the peer device does not support fragment reassembly, you must configure the ppp mp fragment disable command to disable MP fragmentation on the local device.
Views MP-group interface view Predefined user roles network-admin Parameters time: Specifies the maximum LFI fragment transmission delay in the range of 1 to 1000 ms. Examples # Set the maximum LFI fragment transmission delay to 20 ms on interface MP-group 1. system-view [Sysname] interface mp-group 1 [Sysname-MP-group1] ppp mp lfi delay-per-frag 20 Related commands • ppp mp lfi enable • ppp mp lfi size-per-frag ppp mp lfi enable Use ppp mp lfi enable to enable LFI on an interface.
ppp mp lfi size-per-frag Use ppp mp lfi size-per-frag to set the maximum LFI fragment size (in bytes). Use undo ppp mp lfi size-per-frag to restore the default. Syntax ppp mp lfi size-per-frag size undo ppp mp lfi size-per-frag Default The maximum LFI fragment size depends on the configuration of the ppp mp lfi delay-per-frag command. Views MP-group interface view Predefined user roles network-admin Parameters size: Specifies the maximum LFI fragment size in the range of 40 to 1500 bytes.
Predefined user roles network-admin Parameters max-bind-num: Specifies the maximum number of links allowed in an MP bundle, in the range of 1 to 128. Usage guidelines Use the default setting in normal cases. Inappropriate use of this command can cause PPP performance degradation. Make sure you understand the impact of this command on your network before you use it. Configure the maximum number of links allowed in an MP bundle to be greater than the actual number of bundled links.
min-fragment command conforms to the hardware specifications for the MP bundle to be created and the sub-channel LCP link to be established successfully. Examples # Set the minimum MP packet fragmentation size to 500 bytes. system-view [Sysname] interface mp-group 1 [Sysname-MP-group1] ppp mp min-fragment 500 ppp mp mp-group Use ppp mp mp-group to assign an interface to an MP group, enabling the interface to operate in MP mode. Use undo ppp mp to restore the default.
Syntax ppp mp short-sequence undo ppp mp short-sequence Default The long sequence number header format is used. Views Interface view Predefined user roles network-admin Usage guidelines This command applies to the incoming direction only. To enable the local end to transmit packets with short sequence numbers, configure this command on the remote end. The sequence number format (long or short) of an MP bundle depends on the configuration of the first channel joining the MP bundle.
Usage guidelines The MP sort buffer size = the number of channels in the current MP bundle × size. You can use the display ppp mp command to view the number of member channels in an MP bundle. If the calculated MP sort buffer size is 20, the MP sort buffer can sort 20 packets. When MP is used, the received packets might be out of order. The sort buffer is used to re-sort packets. The sort buffer size is a trade-off between re-sorting effect and delay.
Syntax reset counters interface [ mp-group [ interface-number ] ] Views User view Predefined user roles network-admin Parameters mp-group: Clears traffic statistics on MP-group interfaces. interface-number: Specifies an existing MP-group interface by its number. Usage guidelines Before collecting traffic statistics within a specific period of time on an MP-group interface, clear the existing statistics. If you do not specify the mp-group keyword, this command clears statistics on all interfaces.
If you specify the virtual-template keyword without the interface-number argument, this command clears statistics on all VT interfaces. If you specify both virtual-template and interface-number, this command clears statistics on the specified VT interface. Examples # Clear statistics on interface Virtual-Template 10. reset counters interface virtual-template 10 Related commands display interface virtual-template service NOTE: Only the MSR4000 routers support this command.
shutdown Use shutdown to shut down an MP-group interface. Use undo shutdown to bring up an MP-group interface. Syntax shutdown undo shutdown Default An MP-group interface is up. Views MP-group interface view Predefined user roles network-admin Examples # Shut down interface MP-group 3.
PPPoE client commands display pppoe-client session packet Use display pppoe-client session packet to display the protocol packet statistics for a PPPoE session. Syntax display pppoe-client session packet [ dial-bundle-number number ] Views Any view Predefined user roles network-admin network-operator Parameters dial-bundle-number number: Specifies the dialer bundle number corresponding to a PPPoE session, in the range of 0 to 1023.

Predefined user roles network-admin Parameters dial-bundle-number number: Specifies the dialer bundle number corresponding to a PPPoE session, in the range of 0 to 1023. If this option is not specified, this command resets the protocol packet statistics for all PPPoE sessions. Examples # Reset the protocol packet statistics for all PPPoE sessions.
L2TP commands allow l2tp Use allow l2tp to configure an LNS to accept L2TP tunneling requests from a specified LAC, and to specify a VT interface for tunnel setup. Use undo allow to restore the default. Syntax • For L2TP group 1: allow l2tp virtual-template virtual-template-number [ remote remote-name ] undo allow • For L2TP groups other than L2TP group 1: allow l2tp virtual-template virtual-template-number remote remote-name undo allow Default An LNS denies L2TP tunneling requests from any LACs.
HP recommends that you configure a default L2TP group on the LNS in the following cases: • There are LACs (such as hosts with Windows 2000 Beta 2 installed) that include blank local names in their tunneling requests. • The LNS sets up tunnels with multiple LACs by using the same tunnel parameters. Examples # Specify L2TP group 1 as the default L2TP group, and specify Virtual-Template 1 for tunnel setup.
default Use default to restore the default settings for a virtual PPP interface. Syntax default Views Virtual PPP interface view Predefined user roles network-admin Usage guidelines CAUTION: The default command might interrupt ongoing network services. Make sure you are fully aware of the impacts of this command when you execute it in a live network. This command might fail to restore the default settings for some commands for reasons such as command dependencies or system restrictions.
Parameters text: Specifies the interface description, a case-sensitive string of 1 to 80 characters. Examples # Set the description of Virtual-PPP 10 to virtual-interface. system-view [Sysname] interface virtual-ppp 10 [Sysname-Virtual-PPP10] description virtual-interface display interface virtual-ppp Use display interface virtual-ppp to display information about virtual PPP interfaces.
Internet Address is 10.0.0.
Protocol: (s) - spoofing Interface Link Protocol Main IP Description VPPP10 ADM Virtual-PPP10 Interface DOWN 10.0.0.1 # Display information about the virtual PPP interfaces in physically down state and the causes.
Field Description Causes for the physical state of the interface to be Down: • Not connected—No physical connection exists (possibly because the L2TP negotiation fails or insufficient configuration exists to trigger L2TP negotiation). Cause • Administratively—The interface was shut down by using the shutdown command. To restore the physical state of the interface, use the undo shutdown command. display l2tp session Use display l2tp session to display information about L2TP sessions.
Field Description Session state: • Idle. • Wait-tunnel—Waits for the tunnel to be established. • Wait-reply—Waits for an Incoming-Call-Reply (ICRP) State message indicating the call is accepted. • Wait-connect—Waits for an Incoming-Call-Connected (ICCN) message. • Established. display l2tp tunnel Use display l2tp tunnel to display information about L2TP tunnels.
Field Description Sessions Number of sessions within the tunnel. RemoteAddress IP address of the peer. RemotePort UDP port number of the peer. RemoteName Name of the tunnel peer. Related commands reset l2tp tunnel interface virtual-ppp Use interface virtual-ppp to create a virtual PPP interface and enter its view. If the interface has been created, you directly enter its view. Use undo interface virtual-ppp to remove a virtual PPP interface.
undo l2tp enable Default The L2TP function is disabled. Views System view Predefined user roles network-admin Usage guidelines L2TP must be enabled for relevant L2TP configurations to take effect. Examples # Enable the L2TP function. system-view [Sysname] l2tp enable l2tp-auto-client Use l2tp-auto-client to trigger an LAC to automatically establish an L2TP tunnel. Use undo l2tp-auto-client to remove the automatically established L2TP tunnel.
[Sysname-Virtual-PPP1] l2tp-auto-client l2tp-group 10 Related commands l2tp-group l2tp-group Use l2tp-group to create an L2TP group and enter its view. Use undo l2tp-group to remove an L2TP group. Syntax l2tp-group group-number [ mode { lac | lns } ] undo l2tp-group group-number Default No L2TP group exists. Views System view Predefined user roles network-admin Parameters group-number: Specifies an L2TP group by its number in the range of 1 to 65535. mode: Specifies a mode for the L2TP group.
lns-ip Use lns-ip to specify LNS IP addresses on an LAC. Use undo lns-ip to remove the specified LNS IP addresses. Syntax lns-ip { ip-address }&<1-5> undo lns-ip Default No LNS IP addresses are specified. Views L2TP group view Predefined user roles network-admin Parameters { ip-address }&<1-5>: Specifies LNS IP addresses. &<1-5> indicates that you can enter a maximum of five IP addresses.
Predefined user roles network-admin Usage guidelines The LNS uses the LAC as an authentication proxy. The LAC sends the LNS all user authentication information from users and the authentication method configured on the LAC itself. The LNS then checks the user validity according to the received information and the locally configured authentication method.
If you do not expect the LNS to accept LCP negotiation parameters, configure this command to perform a new round of LCP negotiation between the LNS and the user. In this case, the information sent by the LAC will be ignored. Some users might not support LCP renegotiation. In this case, do not configure this command because LCP renegotiation will fail. This command is available only to L2TP groups in LNS mode. This command is effective only on NAS-initiated L2TP tunnels.
reset l2tp tunnel Use reset l2tp tunnel to disconnect a tunnel and all sessions within the tunnel. Syntax reset l2tp tunnel { id tunnel-id | name remote-name } Views User view Predefined user roles network-admin Parameters id tunnel-id: Specifies a tunnel by its local ID in the range of 1 to 65535. name remote-name: Specifies L2TP tunnels by the tunnel peer name, a case-sensitive string of 1 to 31 characters.
Views Virtual PPP interface view Predefined user roles network-admin Parameters slot slot-number: Specifies a card by its slot number. Usage guidelines The service command affects only L2TP data messages. The control messages are always processed on the active MPU. If a card is specified to process traffic for a virtual PPP interface, all traffic forwarded through this virtual PPP interface is encapsulated and decapsulated on the card or IRF member device.
tunnel authentication Use tunnel authentication to enable the L2TP tunnel authentication function. Use undo tunnel authentication to disable the L2TP tunnel authentication function. Syntax tunnel authentication undo tunnel authentication Default L2TP tunnel authentication is enabled. Views L2TP group view Predefined user roles network-admin Usage guidelines Tunnel authentication prevents the local end from establishing L2TP tunnels with illegal remote ends.
Usage guidelines L2TP uses Attribute Value Pairs (AVPs) to transmit tunnel negotiation parameters, session negotiation parameters, and user authentication information. This feature can hide sensitive AVP data, such as user passwords. With this feature enabled, AVP data is encrypted before transmission with the key configured by using the tunnel password command. The tunnel avp-hidden command can be configured for L2TP groups in both LAC and LNS modes, but it does not take effect on L2TP groups in LNS mode.
system-view [Sysname] l2tp-group 1 mode lac [Sysname-l2tp1] tunnel flow-control tunnel name Use tunnel name to specify the local tunnel name. Use undo tunnel name to restore the default. Syntax tunnel name name undo tunnel name Default The local tunnel name is the device name. For more information about the device name, see Fundamentals Configuration Guide.
Predefined user roles network-admin Parameters cipher: Sets a ciphertext key. simple: Sets a plaintext key. password: Specifies the key for tunnel authentication. This argument is case-sensitive. If cipher is specified, it must be a ciphertext string of 1 to 53 characters. If simple is specified, it must be a string of 1 to 16 characters. Usage guidelines For this command to take effect, you must enable tunnel authentication by using the tunnel authentication command.
You can set different Hello intervals for the LNS and LAC. Examples # Set the Hello interval to 90 seconds. system-view [Sysname] l2tp-group 1 mode lac [Sysname-l2tp1] tunnel timer hello 90 ip dscp Use ip dscp to configure the DSCP value of L2TP packets. Use undo ip dscp to restore the default. Syntax ip dscp dscp-value undo ip dscp Default The DSCP value of L2TP packets is 0.
Default The polling interval is 10 seconds. Views Virtual PPP interface view Predefined user roles network-admin Parameters seconds: Specifies the interval at which the LAC or the LNS sends keepalive packets, in the range of 0 to 32767 seconds. Usage guidelines A virtual PPP interface periodically sends keepalive packets to the peer. If the peer fails to receive keepalive packets within 10 keepalive intervals, it considers the link faulty and reports a link layer down event.
fullusername user-name: Specifies that the LAC initiate tunneling requests to the LNS when the username of a user matches a configured full username. The domain-name argument represents the username of the user and is a case-sensitive string of 1 to 255 characters. Usage guidelines This command is available only to L2TP groups in LAC mode. If you execute this command multiple times for an L2TP group, the most recent configuration takes effect.
[Sysname] l2tp-group 1 mode lac [Sysname-l2tp1] vpn-instance vpn1 Related commands • ip vpn-instance (MPLS Command Reference) • ip binding vpn-instance (MPLS Command Reference) 62
HDLC commands This feature is supported only on routers installed with SAE, E1, E1-F, T1, T1-F, POS, CPOS, CT3, or CE3 interface modules. For more information about interface modules, see HP MSR Router Series Interface Module Guide. link-protocol hdlc Use link-protocol hdlc to enable HDLC encapsulation on an interface. Syntax link-protocol hdlc Default PPP encapsulation is enabled on an interface.
Predefined user roles network-admin Parameters seconds: Link status polling interval (in seconds), in the range 0 to 32767. Usage guidelines HDLC can regularly check link status. If an interface uses HDLC as the link layer protocol, the link layer sends keepalive packets to the peer at an interval specified by the timer-hold command. A keepalive packet carries the local sending sequence number and the previous sending sequence number of the peer.
ISDN commands This feature is supported only on routers installed with BS, BU, E1, or T1 interface modules. For more information about interface modules, see HP MSR Router Series Interface Module Guide. display isdn active-channel Use display isdn active-channel to display calling information for calls successfully established through Q.931 on an ISDN interface.

Call property: • Digital. • Analog.
Usage guidelines The output shows ISDN protocol information at each layer on one or all interfaces. ISDN protocols include Q.921, Q.931, and CC. You can use this command to troubleshoot problems. Examples # Display calling information on BRI 2/0.
Field Description TEI Terminal endpoint identifier that indentifies a terminal or user side device such as an ISDN phone. A TEI is assigned by a network side device. Current state of the Layer 2 link of the ISDN interface: • TEI_UNASSIGNED—The TEI is not assigned. • ASSIGN_AWAITING_TEI—Waiting for the TEI to be assigned. • ESTABLISH_AWAITING_TEI—Waiting for the TEI to be assigned and multiple frame establishment. • TEI_ASSIGNED—The TEI is assigned.
Field Description Current state of the Layer 3 link of the BRI interface: • • • • • NULL—No call exists. CALL_INITIATED—Initiates call establishment. OVERLAP_SENDING—Sends called number in overlap mode. OUTGOING_CALL_PROCEEDING—Outgoing call is proceeding. CALL_DELIVERED—The remote user alerting has been initiated but the call has not been answered yet. • CALL_PRESENT—A call establishment request has been received but has not yet responded.
network-operator Parameters interface interface-type interface-number: Specifies a BRI that runs the NI protocol by its type and number. If you do not specify an interface, this command displays SPID information on all the NI-supported BRIs. Usage guidelines You can execute this command to display information such as the SPID type and SPID value when ISDN is running. Examples # Display SPID information on NI-supported interface BRI 2/0 (the SPID type is AUTO).
Table 13 Command output Field Description SPID type: SPID Type • NIT—Not initial terminal mode. • STATIC—Static mode that has only the L3 initialization process. • AUTO—Dynamic mode that includes both the negotiation and the L3 initialization. SPID B1 SPID information for the B1 channel on the BRI. SPID B2 SPID information for the B2 channel on the BRI. SPID Num SPID value of the BRI interface.
Predefined user roles network-admin Parameters exclusive: Specifies the exclusive local management mode for ISDN B channels. When the B channel indicated by the PBX is inconsistent with that required by the local end, the call fails. Usage guidelines It is very important to put appropriate control over B channels used for calls in process, especially in PRI mode. Proper channel management can improve call efficiency and reduce call loss.
Parameters ascending: Selects ISDN B channels in ascending order. descending: Selects ISDN B channels in descending order. Usage guidelines The executing of this command does not take effect when the PBX manages ISDN B channels, or without configuring the isdn bch-local-manage command on the user side. Examples # Set the B channel selection method on BRI 2/0 to descending order.
system-view [Sysname] interface bri 1/0 [Sysname-Bri1/0] isdn bri-slipwnd-size 7 Related commands isdn pri-slipwnd-size isdn caller-number Use isdn caller-number to configure a permitted calling number for incoming calls. Use undo isdn caller-number to delete the configured calling number. Syntax isdn caller-number caller-number undo isdn caller-number Default ISDN accepts all incoming calls without checking the calling numbers in setup messages..
Default No calling number is carried in messages that a calling party transmits. Views ISDN interface view Predefined user roles network-admin Parameters calling-number: Specifies the calling number, a case-insensitive string of 1 to 24 characters.. Usage guidelines After the calling party sends the calling number to the called party, the called party can see the calling number through the display isdn call-info command.
You can execute this command only if no call exists on an ISDN interface.

undo isdn spid nit Default A BRI does not use the NIT mode. The SPID negotiation is used instead. Views ISDN BRI interface view Predefined user roles network-admin Usage guidelines Use this command only on a BRI that runs the NI protocol. A BRI that runs the NI protocol can initiate a call only after SPID negotiation or initialization.
Parameters times: Specifies the number of INFORMATION message retransmission attempts, in the range of 1 to 255. Usage guidelines Use this command only on a BRI that runs the NI protocol. A BRI that runs the NI protocol can initiate a call only after SPID negotiation or initialization. The timer TSPID is started after the device initiates a SPID negotiation or initialization request by sending an INFORMATION message.
During the dynamic negotiation, if the PBX provides multiple SPIDs to the device, the device selects a SPID according to the service type of the current configuration. The SPID that simultaneously supports speech and data services takes precedence by default. If you configure the isdn spid service data command, the device selects the SPID that supports the data service. If you execute this command multiple times, all the service types configured take effect.

Syntax dialer bundle enable undo dialer bundle enable Default No DDR is enabled on a dialer interface. Views Dialer interface view Predefined user roles network-admin Usage guidelines DDR includes C-DDR and B-DDR. Before using B-DDR, you must use this command to enable B-DDR on a dialer interface and then assign physical interfaces to the corresponding dialer bundle by using the dialer bundle-member command.
Predefined user roles network-admin Parameters number: Specifies the dialer bundle number, which is the same as the dialer interface number. priority priority: Specifies the priority of a physical interface in the dialer bundle, in the range of 1 to 255. The higher the number, the higher the priority. The physical interface with a higher priority is used first. The default priority is 1. Usage guidelines This command applies only to physical interfaces.
placing a return call, DDR needs to identify the dial string to be used by comparing the remote username obtained in PPP negotiation against the local user database for a match. Usage guidelines This command is mandatory on the PPP callback server. With both references configured, the device always attempts to place return calls in the user reference approach, and in case failure occurs, place return calls in the dial number reference approach.
Parameters remote-number: ISDN calling number, a case-insensitive string of 1 to 30 characters. The asterisks (*) represent any characters. callback: Enables the device to place a return call if an ISDN calling number matches the number specified by the remote-number argument (starting with the rightmost character). Usage guidelines When receiving an incoming ISDN call, the device with the dialer call-in command configured first verifies that the caller is valid before processing the call.

Views Dialer interface view Predefined user roles network-admin Parameters username: Specifies the remote username for PPP authentication, a case-insensitive string of 1 to 80 characters. Usage guidelines The device checks the remote username obtained in PPP authentication against the remote usernames configured by this command to determine which dialer interface receives which call.
Views Physical interface view Predefined user roles network-admin Parameters priority: Priority of the physical interface in a dialer circular group, in the range of 1 to 127. The larger the value, the higher the priority. Usage guidelines This command sets the order in which the available physical interfaces in a dialer circular group are used. The physical interface with a higher priority is used first. Examples # Set the priority of interface Serial 2/0 in dialer circular group 1 to 5.
# Set the buffer queue length to 10 on interface Serial 2/0. system-view [Sysname] interface serial 2/0 [Sysname-Serial2/0] dialer queue-length 10 dialer route Use dialer route to enable a DDR interface to call the specified destination address (host or network address) or to receive calls from multiple remote ends. Use undo dialer route to remove a dialer route.
If you specify the dial-number argument in the dialer route command, you must also include the dial-number argument when using the undo dialer route command to remove the dialer route. If the user keyword is used, PPP authentication must be configured. DDR accepts a call only when the peer username obtained through PPP authentication is the same as the remote username configured by using this command.
If you set a link load threshold in the range of 1 to 99, MP tunes allocated bandwidth according to actual traffic percentage following these guidelines: • When the percentage of traffic on a link to bandwidth exceeds the defined traffic threshold, the system automatically brings up a second link, and assigns the two links to one MP bundle.
Parameters seconds: Specifies the interval between call attempts, in the range of 1 to 604800 seconds. Usage guidelines This command takes effect only when the autodial keyword is configured in the dialer number or dialer route command. It allows DDR to automatically dial at certain intervals to set up a connection. In the auto-dial approach, dial attempts to set up a connection are not traffic triggered. Once a connection is set up, it will not disconnect for idle-timeout.
[Sysname-Serial2/0] dialer timer compete 10 dialer timer enable Use dialer timer enable to set the link holddown timer. Use undo dialer timer enable to restore the default. Syntax dialer timer enable seconds undo dialer timer enable Default The link holddown timer is 5 seconds. Views Dialup interface (physical or dialer interface) view Predefined user roles network-admin Parameters seconds: Holddown timer value, setting the interval for originating a call to bring up a link after it is disconnected.
Views Dialup interface (physical or dialer interface) view Predefined user roles network-admin Parameters seconds: Link idle-timeout timer, setting the time that a link is allowed to be idle. The value range for this argument is 0 to 65535 seconds. in: Specifies that only incoming interesting packets reset the timer. in-out: Specifies that both incoming and outgoing interesting packets reset the timer. Usage guidelines A link idle-timeout timer starts upon setup of a link.
Usage guidelines Sometimes, the time that DDR waits for a connection to be established might vary call by call. To handle this situation, you can use a wait-carrier timer. A wait-carrier timer starts when a call is placed. If the connection is not established upon expiration of the timer, DDR terminates the call. Examples # Set the wait-carrier timer to 100 seconds on interface Serial 2/0.

Output queue: (Urgent queuing : Length) Statistics on the packets in the urgent output queue. Output queue: (Protocol queuing : Length) Statistics on the packets in the protocol output queue. Output queue: (FIFO queuing : Length) Statistics on the packets in the FIFO output queue.
Related commands reset counters interface interface dialer Use interface dialer to create a dialer interface. In C-DDR, this is the same as creating a dialer circular group. Use undo interface dialer to remove a dialer interface. Syntax interface dialer number undo interface dialer number Default No dialer interface is created. Views System view Predefined user roles network-admin Parameters number: Dialer interface number in the range of 0 to 1023.
mtu Use mtu to set the MTU of a dialer interface. Use undo mtu to restore the default. Syntax mtu size undo mtu Default The MTU of dialer interfaces is 1500 bytes. Views Dialer interface view Predefined user roles network-admin Parameters size: Specifies the maximum transmission unit (MTU) in the range of 128 to 1500 bytes. Usage guidelines The MTU setting of a dialer interface affects the fragmentation and reassembly of IP packets. Examples # Set the MTU of interface Dialer 1 to 1200 bytes.
If neither dialer nor interface-number is specified, this command clears the statistics of all the interfaces. If only dialer is specified, this command clears the statistics of all dialer interfaces. If both dialer and interface-number are specified, this command clears the statistics of the specified dialer interface. Examples # Clear the statistics of Dialer 1. reset counters interface dialer 1 Related commands display interface dialer shutdown Use shutdown to shut down a dialer interface.
Views Dialup interface view Predefined user roles network-admin Parameters group-number: Dynamic route backup group number in the range of 1 to 255. Usage guidelines Before enabling the dynamic route backup function on a dialup interface, make sure DDR is enabled on the interface. Examples # Enable the dynamic route backup function on interface BRI 3/0.
Usage guidelines Up to 255 monitored network segments can be added to a dynamic route backup group. The primary link is considered to be disconnected only when the routes to all the monitored network segments in a dynamic route backup group become invalid. Examples # Create dynamic route backup group 1 to monitor routes to the network segments 20.0.0.0/8 and 30.0.0.0/8. system-view [Sysname] standby routing-group 1 rule ip 20.0.0.1 255.0.0.0 [Sysname] standby routing-group 1 rule ip 30.0.0.1 255.
Default The interval for sending keepalive packets is 10 seconds. Views Dialer interface view Predefined user roles network-admin Parameters seconds: Interval (in seconds) for sending keepalive packets, in the range of 0 to 32767. The value 0 disables keepalive packet sending. Usage guidelines The polling interval specifies the interval at which an interface sends keepalive packets.
