Interface backup commands backup interface Use backup interface to specify a backup interface for an interface. Use undo backup interface to remove a backup interface. Syntax backup interface interface-type interface-number [ priority ] undo backup interface interface-type interface-number Default An interface does not have backup interfaces. Views Interface view Predefined user roles network-admin Parameters interface-type interface-number: Specifies a backup interface by its type and number.
Item Restrictions • An interface can only be the backup of one interface. • A primary interface cannot be configured as a backup interface at the same time. Configuration restrictions • A main interface and its subinterfaces cannot be the backup of each other. • The primary and backup interfaces cannot be members of a logical link. For example, they cannot be members of a Layer 3 aggregation group. This command and the backup track command are mutually exclusive.
NOTE: To set the bandwidth used for load sharing calculation in this command, use the bandwidth command on the primary interface. Usage guidelines Before you can use this command on an interface, you must specify at least one backup interface for the interface. This command enables a primary interface and its backup interfaces to be load shared. In load sharing mode, interface backup regularly compares the amount of traffic with the thresholds.
Predefined user roles network-admin Parameters up-delay: Specifies the number of seconds that the primary or backup interface must wait before it can come up. The value range is 1 to 65535 seconds. down-delay: Specifies the number of seconds that the active primary or backup interface must wait before it is set to down state. The value range is 1 to 65535 seconds. Usage guidelines Before you can use this command on an interface, you must specify at least one backup interface for the interface.
Usage guidelines Before you can use this command on an interface, you must specify at least one backup interface for the interface. This command takes effect when the primary and backup interfaces operate in load sharing mode. Interface backup compares the amount of traffic with the thresholds at this interval to determine whether to activate or deactivate a backup interface. Examples # Set the traffic polling interval to 60 seconds on Serial 2/1/0.
• If you have associated a backup interface with a track entry, you cannot configure the backup interface command on it or specify it as a backup interface by using the backup interface command. Examples # Associate Serial 2/1/0 with track entry 1. system-view [Sysname] interface serial 2/1/0 [Sysname-Serial2/1/0] backup track 1 Related commands backup interface display interface-backup state Use display interface-backup state to display state information for primary and backup interfaces.
GE2/1/8 Track: 2 State: UP Table 2 Command output Field Description Interface Name of the primary interface. UpDelay The number of seconds that elapse after the primary interface goes down before the backup interface is activated. DownDelay The number of seconds that elapse after the primary interface comes up before the backup interface is deactivated. The upper traffic threshold specified as a percentage of bandwidth available on the primary interface.
Field Description State of the backup interface associated with a track entry: INVALID—The backup role of the interface has not taken effect, for example, because the track entry has not been created. UP—The interface has taken over forwarding traffic. State DOWN—The backup interface is down and cannot forward traffic. STANDBY—The backup interface is on standby while the primary link is operating correctly.
Field Description Bandwidth Expected bandwidth (in bps) of the primary interface. This bandwidth is used for load sharing computation. You can use the bandwidth command in interface view to set its value. PrimaryTotalIn Cumulative sum of incoming bytes on the primary interface at the most recent traffic polling. PrimaryTotalOut Cumulative sum of outgoing bytes on the primary interface at the most recent traffic polling.
VRRP commands VRRP cannot be configured on member ports of aggregation groups. IPv4 VRRP commands display vrrp Use display vrrp to display the states of IPv4 VRRP groups.

• If only an interface is specified, this command clears statistics for all IPv4 VRRP groups on the specified interface. • If both an interface and an IPv4 VRRP group are specified, this command clears statistics for the specified IPv4 VRRP group on the specified interface. Examples # Clear statistics for all IPv4 VRRP groups on all interfaces.
Syntax vrrp check-ttl enable undo vrrp check-ttl enable Default TTL check for IPv4 VRRP packets is enabled. Views Interface view Predefined user roles network-admin Usage guidelines The master in an IPv4 VRRP group periodically sends VRRP advertisements to declare its presence. The VRRP advertisements are multicast in the local subnet and cannot be forwarded by routers, so the TTL value is not changed. When the master sends VRRP advertisements, it sets the TTL value to 255.
Parameters vid vlan-id: Specifies an IPv4 VRRP control VLAN (outer VLAN) by its VLAN ID in the range of 1 to 4094. secondary-dot1q secondary-vlan-id: Specifies an inner VLAN by its VLAN ID in the range of 1 to 4094. Usage guidelines If you execute this command multiple times, the most recent configuration takes effect. This command takes effect on only Layer 3 Ethernet subinterfaces and Layer 3 aggregate subinterfaces.
undo vrrp mode Default IPv4 VRRP operates in standard mode. Views System view Predefined user roles network-admin Parameters load-balance: Specifies the load balancing mode. Usage guidelines After you create IPv4 VRRP groups on the router, you can specify their operating mode by using this command. All IPv4 VRRP groups on the router operate in the specified mode. Examples # Specify the load balancing mode for IPv4 VRRP.
system-view [Sysname] interface gigabitethernet 2/0/1 [Sysname-GigabitEthernet2/0/1] vrrp version 2 vrrp vrid authentication-mode Use vrrp vrid authentication-mode to configure the authentication mode and the authentication key for an IPv4 VRRP group to send and receive VRRP packets. Use undo vrrp vrid authentication-mode to restore the default.
For security purposes, all keys, including keys configured in plain text, are saved in cipher text. IMPORTANT: • You can configure different authentication modes and authentication keys for the VRRP groups on an interface. However, members of the same VRRP group must use the same authentication mode and authentication key. • For VRRPv3, this command does not take effect. Examples # Set the authentication mode to simple and the authentication key to Sysname for VRRP group 1 on GigabitEthernet 2/0/1.
In preemptive mode, a backup takes over as the master and sends VRRP advertisements when it detects that it has a higher priority than the master. The previous master then becomes a backup. This mechanism makes sure the master is always the device with the highest priority.

Related commands reset vrrp ipv6 statistics reset vrrp ipv6 statistics Use reset vrrp ipv6 statistics to clear statistics for IPv6 VRRP groups. Syntax reset vrrp ipv6 statistics [ interface interface-type interface-number [ vrid virtual-router-id ] ] Views User view Predefined user roles network-admin Parameters interface interface-type interface-number: Specifies an interface by its type and number. vrid virtual-router-id: Specifies an IPv6 VRRP group by its virtual router ID in the range of 1 to 255.
Usage guidelines The DSCP value identifies the packet priority during transmission. A greater DSCP value means a higher packet priority. Examples # Configure the DSCP value for IPv6 VRRP packets as 30. system-view [Sysname] vrrp ipv6 dscp 30 vrrp ipv6 mode Use vrrp ipv6 mode to specify the operating mode for IPv6 VRRP. Use undo vrrp ipv6 mode to restore the default. Syntax vrrp ipv6 mode load-balance undo vrrp ipv6 mode Default IPv6 VRRP operates in standard mode.
Use undo vrrp ipv6 vrid preempt-mode to disable the preemptive mode for the router in an IPv6 VRRP group. Use undo vrrp ipv6 vrid preempt-mode delay to restore the default preemption delay. Syntax vrrp ipv6 vrid virtual-router-id preempt-mode [ delay delay-value ] undo vrrp ipv6 vrid virtual-router-id preempt-mode [ delay ] Default The router operates in preemptive mode and the preemption delay is 0 seconds.
undo vrrp ipv6 vrid virtual-router-id priority Default The priority of a router in an IPv6 VRRP group is 100. Views Interface view Predefined user roles network-admin Parameters virtual-router-id: Specifies an IPv6 VRRP group by its virtual router ID in the range of 1 to 255. priority-value: Specifies a priority value in the range of 1 to 254. A higher number indicates a higher priority. Usage guidelines VRRP determines the role (master or backup) of each router in a VRRP group by priority.
Parameters virtual-router-id: Specifies an IPv6 VRRP group by its virtual router ID in the range of 1 to 255. Usage guidelines You can use this command to temporarily disable an IPv6 VRRP group. After this command is configured, the VRRP group stays in initialized state, and its configurations remain unchanged. You can change its configuration, and your changes take effect when you enable the VRRP group again. Examples # Disable IPv6 VRRP group 1.
Large network traffic might disable a backup from receiving VRRP advertisements from the master within the specified time and trigger an unexpected master switchover. To solve this problem, you can use this command to configure a larger interval. Examples # Configure the master in IPv6 VRRP group 1 to send VRRP advertisements at an interval of 500 centiseconds.
When the track entry changes from Negative to Positive or NotReady, the router automatically restores its priority. IMPORTANT: • The vrrp ipv6 vrid track command cannot take effect on an IP address owner. If you have configured the command on an IP address owner, the configuration takes effect after the router changes to be a non-IP address owner. • You can create a track entry with the track command before or after you associate it with an IPv6 VRRP group.
The first virtual IPv6 address that you assign for an IPv6 VRRP group must be a link-local address, and it must be removed last. An IPv6 VRRP group can have only one link-local address as its virtual IPv6 address. If you create an IPv6 VRRP group but do not assign any virtual IPv6 address for it, the VRRP group stays in inactive state and does not function.
Usage guidelines This command is effective only when IPv6 VRRP operates in load balancing mode. When the state of the track entry transits to Positive or NotReady, the original weight values of the VFs restore. By default, the weight of a VF is 255, and its lower limit of failure is 10. When the weight of a VF owner is higher than or equal to the lower limit of failure, its priority is always 255 and does not change with the weight.
BFD commands bfd authentication-mode Use bfd authentication-mode to configure the BFD authentication mode for single-hop BFD control packets. Use undo bfd authentication-mode to restore the default. Syntax bfd authentication-mode simple key-id { cipher cipher-string | plain plain-string } undo bfd authentication-mode Default Single-hop BFD control packets are not authenticated. Views Interface view Predefined user roles network-admin Parameters simple: Specifies the simple authentication mode.
Syntax bfd demand enable undo bfd demand enable Default The BFD session is in Asynchronous mode. Views Interface view Predefined user roles network-admin Usage guidelines In demand mode, no BFD control packets are exchanged after the session is established. When the connectivity to another system needs to be verified explicitly, a system sends several BFD control packets that have the Poll (P) bit set at the negotiated transmit interval.
Usage guidelines The member ports in Layer 3 aggregation groups do not have IP addresses, and they do not support fast detection mechanisms. You can use this command to detect link faults and locate the faulty member ports of Layer 3 aggregate interfaces. You can also configure this command on common Layer 3 Ethernet interfaces to implement fast collaboration between interface state and BFD session state, and help routing protocols complete convergence.
Mode Detection interval Control packet mode BFD session in demand mode Detection time multiplier of the sender × actual packet sending interval of the sender Examples # Configure the single-hop detection time multiplier as 6 on GigabitEthernet 2/0/1. system-view [Sysname] interface gigabitethernet 2/0/1 [Sysname-GigabitEthernet2/0/1] bfd detect-multiplier 6 bfd echo enable Use bfd echo enable to enable the echo packet mode. Use undo bfd echo enable to restore the default.
Default No source IP address is configured for BFD echo packets. Views System view Predefined user roles network-admin Parameters ip-address: Specifies the source IP address of BFD echo packets. Usage guidelines The source IP address cannot be on the same network segment as any local interface's IP address. Otherwise, a large number of ICMP redirect packets might be sent from the peer, resulting in link congestion. Examples # Configure the source IP address of BFD echo packets as 8.8.8.8.
system-view [Sysname] bfd echo-source-ipv6 80::2 bfd min-echo-receive-interval Use bfd min-echo-receive-interval to configure the minimum interval for receiving BFD echo packets. Use undo bfd min-echo-receive-interval to restore the default. Syntax bfd min-echo-receive-interval value undo bfd min-echo-receive-interval Default The minimum interval for receiving BFD echo packets is 1000 milliseconds.
Predefined user roles network-admin Parameters value: Specifies the minimum interval for receiving single-hop BFD control packets, in the range of 10 to 10000 milliseconds. Usage guidelines Configure this command to prevent the control packet sending rate of the peer end from exceeding the control packet receiving rate of the local end.
Examples # Configure the minimum interval for transmitting single-hop BFD control packets on GigabitEthernet 2/0/1 as 500 milliseconds. system-view [Sysname] interface gigabitethernet 2/0/1 [Sysname-GigabitEthernet2/0/1] bfd min-transmit-interval 500 bfd multi-hop authentication-mode Use bfd multi-hop authentication-mode to configure the authentication mode for multihop BFD control packets. Use undo bfd multi-hop authentication-mode to restore the default.
bfd multi-hop destination-port Use bfd multi-hop destination-port to configure the destination port number for multihop BFD control packets. Use undo bfd multi-hop destination-port to restore the default. Syntax bfd multi-hop destination-port port-number undo bfd multi-hop destination-port Default The destination port number for multihop BFD control packets is 4784.
Table 17 Detection interval calculation method Mode Detection interval Control packet mode BFD session in asynchronous mode Detection time multiplier of the receiver × actual packet sending interval of the receiver Control packet mode BFD session in demand mode Detection time multiplier of the sender × actual packet sending interval of the sender Examples # Configure the multihop detection time multiplier as 6.
Use undo bfd multi-hop min-transmit-interval to restore the default. Syntax bfd multi-hop min-transmit-interval value undo bfd multi-hop min-transmit-interval Default The minimum interval for transmitting multihop BFD control packets is 1000 milliseconds. Views System view Predefined user roles network-admin Parameters value: Specifies the minimum interval for transmitting multihop BFD control packets, in the range of 10 to 10000 milliseconds.
passive: Uses the passive mode. In passive mode, BFD does not actively transmit a BFD control packet to the remote end; it transmits a BFD control packet only after receiving a BFD control packet from the remote end. Usage guidelines At least one end must operate in active mode for a BFD session to be established. Examples # Configure the session establishment mode as passive.

Views Placement process view Predefined user roles network-admin Parameters program-name: Specifies the name of a process, a case-insensitive string of 1 to 15 characters.
undo affinity self Default No self affinity is configured for any process. Views Placement process view Predefined user roles network-admin Parameters attract strength: Specifies a positive affinity in the range of 1 to 100000. The higher the value, the stronger the preference for all the instances of the current process to run on the same location. default: Sets the affinity to the default, a positive affinity of 200.
Parameters program-name: Specifies a service group by its name, a case-insensitive string of 1 to 15 characters. all: Specifies all service groups running on the device. instance instance-name: Specifies an instance by its name, a case-insensitive string of 1 to 15 characters. Whether or not a service group has multiple instances depends on the system software. Examples # Display the location and status of all service groups.
Field Description Process status: State • • • • • Realtime Backup Batch Backup Stopping Degrading Upgrading display placement location Use display placement location to display the processes running on a specific location. Syntax display placement location { all | slot slot-number [ cpu cpu-number ] } Views Any view Predefined user roles network-admin network-operator Parameters all: Displays all processes running on the device. slot slot-number: Displays the processes running on a card.

Usage guidelines The information about a placement policy is displayed only when the placement policy is configured for the specified process. Examples # Display the default process placement policy. display placement policy program default Program: [default] : source ---------------------------------------------------------affinity location-set slot 0 cpu 0 attract : system [default] # Display the placement policy for AAA.
aaa 0/0 Table 22 Command output Field Description Program Process name. Location of the process. Placed at location If NA is displayed, the process is not available because the service is abnormal or the process is starting up or shut down. display placement reoptimize Use display placement reoptimize to display the predicted changes that will occur when you run the placement reoptimize command.
placement program Use placement program to enter placement process view. Use undo placement program to delete the placement policy for a process. Syntax placement program { program-name [ instance instance-name ] | default } undo placement program { program-name [ instance instance-name ] | default } Default No placement process view is created, and all active processes run on the active CPU.
