Type: A - access; T - trunk; H - hybrid Interface Link Speed XGE1/0/3 UP Duplex Type PVID Description 10G(a) F(a) A 1 aaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa # Display information about interfaces in DOWN state and the causes.
Field Description Description Interface description configured by using the description command. If the description keyword is not specified in the display interface brief command, the Description field displays at most 27 characters. If the description keyword is specified in the display interface brief command, the field displays the full interface description. The brief information of interface(s) under bridge mode: Brief information about Layer 2 interfaces.
Field Description Cause for the physical link state of an interface to be DOWN: • Administratively—The port is manually shut down with the shutdown command. To restore the physical state of the interface, use the undo shutdown command. • DOWN ( Link-Aggregation interface down )—When an aggregate interface is shut down, the physical state of all member ports of the aggregate interface becomes DOWN, and the Cause field displays DOWN ( Link-Aggregation interface down ).
Parameters interface-type: Specifies an interface type. If you do not specify an interface type, this command displays information about dropped packets on all the interfaces on the device. interface-number: Specifies an interface number. If you specify an interface type only, this command displays information about dropped packets on the specified type of interfaces. summary: Displays the summary of dropped packets on all interfaces.
mdc-admin Parameters auto: Configures the interface to autonegotiate the duplex mode with the peer. full: Configures the interface to operate in full duplex mode, so that the interface can receive and transmit packets at the same time. half: Configures the interface to operate in half duplex mode, so that the interface can only receive or only transmit packets at one time. Usage guidelines Copper ports operating at 1000 Mbps or 10000 Mbps and fiber ports do not support the half keyword.
Examples # Enable TxRx mode generic flow control on the interface Ten-GigabitEthernet 1/0/1. system-view [Sysname] interface ten-gigabitethernet 1/0/1 [Sysname-Ten-GigabitEthernet1/0/1] flow-control flow-control receive enable Use flow-control receive enable to enable Rx mode generic flow control on an Ethernet port. Use undo flow-control to disable generic flow control on an Ethernet interface.
Use undo flow-interval to restore the default interval. Syntax flow-interval interval undo flow-interval Default The interface statistics polling interval is 300 seconds. Views Ethernet interface view Predefined user roles network-admin mdc-admin Parameters interval: Sets the statistics polling interval, in seconds. The interval is in the range of 5 to 300 and must be a multiple of 5. Examples # Set the statistics polling interval to 100 seconds on Ten-GigabitEthernet 1/0/1.
jumboframe enable Use jumboframe enable to allow jumbo frames within the specified length to pass through. Use undo jumboframe enable to prevent jumbo frames from passing through. Syntax jumboframe enable [ value ] undo jumboframe enable Default The device allows jumbo frames within 9216 bytes to pass through. Views Ethernet interface view Predefined user roles network-admin mdc-admin Parameters value: Sets the maximum length of Ethernet frames that are allowed to pass through.
mdc-admin Parameters delay-time: Sets the physical state change suppression interval (in seconds) on the Ethernet interface. The value range for this argument is 0 to 30. A value of 0 indicates that physical state changes are immediately reported to the CPU and are not suppressed. mode up: Suppresses the link-up events. mode updown: Suppresses both the link-up and link-down events.
Parameters external: Performs an external loopback test on the Ethernet interface. internal: Performs an internal loopback test on the Ethernet interface. Usage guidelines If an Ethernet interface does not work correctly, you can perform a loopback test on it to identify the problem. An Ethernet interface in a loopback test does not forward data traffic. On a physically down interface (displayed as in DOWN state), you can only perform an internal loopback test, and an external loopback test will fail.
After you change the link mode of an Ethernet interface, all the commands (except the shutdown command) on the Ethernet interface are restored to their defaults in the new link mode. Examples # Configure Ten-GigabitEthernet 1/0/1 to operate in bridge mode. system-view [Sysname] interface ten-gigabitethernet 1/0/1 [Sysname-Ten-GigabitEthernet1/0/1] port link-mode bridge port up-mode Use port up-mode to forcibly bring up a fiber port. Use undo port up-mode to restore the default.
Use priority-flow-control to enable PFC on an Ethernet interface through automatic negotiation or forcibly. Use undo priority-flow-control to disable PFC on the interface. Syntax priority-flow-control { auto | enable } undo priority-flow-control Default PFC is disabled on Ethernet interfaces. Views System view, Ethernet interface view Predefined user roles network-admin mdc-admin Parameters auto: Specifies the Ethernet interface to automatically negotiate with its peer to enable PFC.
Related commands priority-flow-control no-drop dot1p priority-flow-control no-drop dot1p IMPORTANT: This command is applicable to only SF cards. Use priority-flow-control no-drop dot1p to enable PFC for specific 802.1p priorities on an Ethernet interface. Use undo priority-flow-control no-drop dot1p to restore the default. Syntax priority-flow-control no-drop dot1p dot1p-list undo priority-flow-control no-drop dot1p Default PFC is disabled for all 802.1p priorities.
Table 9 The relationship between the PFC function and the generic flow control function flow-control Unconfigurable priority-flowcontrol enable Configured priority-flow-cont rol no-drop dot1p Remarks Configured You cannot enable flow control by using the flow-control command on a port where PFC is enabled and PFC is enabled for the specified 802.1p priority values. • On a port configured with the flow-control command, you can enable PFC, but you cannot enable PFC for specific 802.1p priorities.
Views User view Predefined user roles network-admin mdc-admin Parameters interface-type: Specifies an interface type. interface-number: Specifies an interface number. Usage guidelines Before collecting traffic statistics for a specific period of time on an interface, clear the old statistics first. If no interface type is specified, this command clears statistics for all interfaces. If only the interface type is specified, this command clears statistics for all interfaces of that type.
Parameters slot slot-number: Clears the Ethernet statistics on the specified card. The slot-number argument represents the number of the slot that houses the card. (In standalone mode.) chassis chassis-number slot slot-number: Clears the Ethernet statistics on the specified card of the specified IRF member device. The chassis-number argument represents the ID of the IRF member device. The slot-number argument represents the number of the slot that houses the card. (In IRF mode.
Syntax shutdown undo shutdown Default Ethernet interfaces are in up state. Views Ethernet interface view Predefined user roles network-admin mdc-admin Usage guidelines You might need to shut down and then bring up an Ethernet interface to make some interface configurations take effect. Examples # Shut down and then bring up Ten-GigabitEthernet 1/0/1.
10000: Sets the interface speed to 10000 Mbps. 40000: Sets the interface speed to 40000 Mbps. auto: Enables the interface to negotiate a speed with its peer. Usage guidelines For a copper Ethernet interface, use the speed command to set its speed to match the rate of its peer. For a fiber port, use the speed command to set its speed to match the rate of a transceiver module. Table 10 shows the support of interfaces for the keywords.
Usage guidelines If you need higher bandwidth, you can combine four 10-GE interfaces that are split from a 40-GE interface into a 40-GE interface. To make this command take effect on the four split 10-GE interfaces, execute this command on only one of the split 10-GE interfaces. After this command is successfully configured, the system prompts you to reboot the card that houses the four split 10-GE interfaces.
The 10-GE interfaces that are split from a 40-GE interface support the same configuration and attributes as common 10-GE interfaces, except that they are numbered differently. After this command is successfully configured, the system prompts you to reboot the card that houses the 40-GE interface. You must reboot the card and then the system deletes the 40-GE interface and creates the four 10-GE interfaces. Examples # Split 40-GE interface FortyGigE 1/0/1 into four 10-GE interfaces.
kbps max-kbps: Specifies the maximum number of kilobits of broadcast traffic that the Ethernet interface can forward per second. The value range for this argument (in kbps) is 0 to the maximum interface rate. Usage guidelines You can use the broadcast storm suppression function to limit the size of broadcast traffic on an interface. When the broadcast traffic on the interface exceeds this threshold, the system drops packets until the traffic drops below this threshold.
Parameters broadcast: Displays broadcast storm control settings and statistics. multicast: Displays multicast storm control settings and statistics. unicast: Displays unknown unicast storm control settings and statistics. interface interface-type interface-number: Specifies an interface by its type and number. Usage guidelines If you specify no argument or keyword, this command displays all storm control settings on all storm control-enabled interfaces.
Field Description Status of the storm control threshold event trap switch: Trap • on—The port sends threshold event traps. • off—The port does not send threshold event traps. Status of the storm control threshold event log switch: Log SwitchNum • on—The port sends threshold event log messages. • off—The port does not send threshold event log messages. Number of forwarding state changes of the interface. When the SwitchNum count reaches 65535, it resets automatically.
multicast-suppression Use multicast-suppression to enable multicast storm suppression and set the multicast storm suppression threshold. Use undo multicast-suppression to restore the default. Syntax multicast-suppression { ratio | pps max-pps | kbps max-kbps } undo multicast-suppression Default Ethernet interfaces do not suppress multicast traffic.
Examples # Set the multicast storm suppression threshold to 10000 kbps on Ten-GigabitEthernet 1/0/1. system-view [Sysname] interface ten-gigabitethernet 1/0/1 [Sysname-Ten-GigabitEthernet1/0/1] multicast-suppression kbps 10000 The actual value is 10048 on port Ten-GigabitEthernet1/0/1 currently. Related commands • broadcast-suppression • unicast-suppression storm-constrain Use storm-constrain to enable broadcast, multicast, or unknown unicast storm control on an Ethernet port.
particular type of traffic exceeds its upper threshold, the interface takes a certain action, which can be configured by using the storm-constrain control command. Either of the storm-constrain, broadcast-suppression, multicast-suppression, and unicast-suppression commands can suppress storm on a port. The storm-constrain command uses software to suppress traffic, and affects the device performance to a certain extent.
Views Layer 2 Ethernet interface view Predefined user roles network-admin mdc-admin Parameters block: Blocks this type of traffic, while forwarding other types of traffic. Even though the interface does not forward the blocked traffic, it still counts the traffic. When the blocked traffic is detected dropping below the lower threshold, the port begins to forward the traffic. shutdown: Shuts down automatically. The interface shuts down automatically and stops forwarding any traffic.
system-view [Sysname] interface ten-gigabitethernet 1/0/1 [Sysname-Ten-GigabitEthernet1/0/1] storm-constrain enable log storm-constrain enable trap Use storm-constrain enable trap to enable an Ethernet interface to send storm control threshold event traps. Use undo storm-constrain enable trap to disable trap sending.
Parameters seconds: Sets the traffic polling interval of the storm control module. The value range is 1 to 300 seconds. Usage guidelines The interval set by the storm-constrain interval command is specific to storm control. To set the statistics polling interval of an interface, use the flow-interval command. For network stability, use the default or a higher polling interval. Examples # Set the traffic statistics polling interval of the storm control module to 60 seconds.
Usage guidelines You can use the unicast storm suppression function to limit the size of unicast traffic on an interface. When the unicast traffic on the interface exceeds this threshold, the system discards packets until the unicast traffic drops below this threshold. Both the storm-constrain and unicast-suppression can suppress unicast storm on a port. The storm-constrain command uses software to suppress unicast traffic, and it affects the device performance to a certain extent.
The test result is for reference only. The cable length detection error is up to 5 m (about 16 ft). If a test item is not available, a hyphen (-) is displayed. Examples # Enable cable connection test on interface Ten-GigabitEthernet 1/0/1.
Loopback, null, and inloopback interface commands bandwidth Use bandwidth to configure the expected bandwidth of an interface. Use undo bandwidth to restore the default.

Default TC-BPDU transmission restriction is disabled. Views Layer 2 Ethernet interface view, Layer 2 aggregate interface view Predefined user roles network-admin mdc-admin Usage guidelines When TC-BPDU transmission restriction is enabled on a port, the port does not send TC-BPDUs to other ports, and it does not delete MAC address entries. When the setting is configured in Layer 2 Ethernet interface view, it takes effect on only that interface.
Usage guidelines The forward delay timer determines the time interval of state transition. To prevent temporary loops, a spanning tree port goes through the learning (intermediate) state before it transits from the discarding state to the forwarding state. To stay synchronized with the remote device, the port has a wait period between transition states that is determined by the forward delay timer. HP recommends not setting the forward delay with this command.
protocols automatically calculate the optimal settings for the hello timer. If the network diameter uses the default value, the hello timer also uses the default value.

Usage guidelines LLDP neighbors must use the same data type for the value field in the management address TLV.
Use undo lldp mode to restore the default. Syntax lldp mode service-bridge undo lldp mode Default LLDP operates in customer bridge mode. Views System view Predefined user roles network-admin mdc-admin Parameters service-bridge: Specifies the service bridge mode. Usage guidelines You can use this command to control the LLDP agent types supported by the device: • In service bridge mode, LLDP supports nearest bridge agents and nearest non-TPMR bridge agents.

undo lldp agent nearest-customer tlv-enable { basic-tlv { all | port-description | system-capability | system-description | system-name | management-address-tlv } | dot1-tlv { all | port-vlan-id | link-aggregation } } In Layer 3 Ethernet interface view: • lldp tlv-enable { basic-tlv { all | port-description | system-capability | system-description | system-name | management-address-tlv [ ip-address ] } | dot1-tlv { all | link-aggregation } | dot3-tlv { all | mac-physic | max-frame-size | power } | med-tlv
• Nearest bridge agents can advertise all types of LLDP TLVs (only link aggregation TLV in 802.1 organizationally specific TLVs) except network policy TLVs. • Nearest non-TPMR bridge agents advertise no TLVs. • Nearest customer bridge agents can advertise basic TLVs and IEEE 802.1 organizationally specific TLVs (only link aggregation TLV). On Layer 2 aggregate interfaces: • Nearest non-TPMR bridge agents can advertise only EVB TLVs.
evb: Advertises the EVB module TLVs. port-vlan-id: Advertises port VLAN ID TLVs. protocol-vlan-id [ vlan-id ]: Advertises port and protocol VLAN ID TLVs. The vlan-id argument specifies a VLAN ID in the TLVs to be advertised. The VLAN ID is in the range of 1 to 4094, and the default is the lowest VLAN ID on the port. vlan-name [ vlan-id ]: Advertises VLAN name TLVs. The vlan-id argument specifies a VLAN ID in the TLVs to be advertised.
If the MAC/PHY configuration/status TLV is not advertisable, none of the LLDP-MED TLVs will be advertised regardless of whether they are advertisable. If the LLDP-MED capabilities TLV is not advertisable, the other LLDP-MED TLVs will not be advertised regardless of whether they are advertisable. The port and protocol VLAN ID TLV, VLAN name TLV, and management VLAN ID TLV in IEEE 802.1 organizationally specific LLDP TLVs can be configured only for nearest bridge agents.
Service loopback group commands display service-loopback group Use display service-loopback group to display information about service loopback groups. Syntax display service-loopback group [ number ] Views Any view Predefined user roles network-admin network-operator mdc-admin mdc-operator Parameters number: Specifies a service loopback group ID in the range of 1 to 1024. If you do not specify a service loopback group, this command displays information about all service loopback groups.
Syntax port service-loopback group number undo port service-loopback group Default The service loopback group does not contain ports. Views Layer 2 Ethernet interface view Predefined user roles network-admin mdc-admin Parameters number: Specifies a service loopback group ID in the range of 1 to 1024. Usage guidelines Before assigning a port to a service loopback group, make sure the port supports the service type of the group. You can assign up to 32 ports to the service loopback group.
type: Specifies the service type of the service loopback group. tunnel: Specifies the unicast tunnel service. Usage guidelines The device supports only one service loopback group. The service loopback group must work with other features, such as GRE. It can be used by multiple features. You must create the service loopback group before you can use it with a feature. For correct traffic processing, do not delete a service loopback group that is being used by a feature.
