EVB commands bandwidth Use bandwidth to configure the expected bandwidth of an S-channel interface or a VSI. Use undo bandwidth to restore the default. Syntax bandwidth bandwidth-value undo bandwidth Default The expected bandwidth of an S-channel interface or a VSI is the default maximum bandwidth of the physical port to which the S-channel interface or the VSI belongs.
Predefined user roles network-admin mdc-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 on a live network. This command might fail to restore the default settings for some commands for reasons such as command dependencies and system restrictions. Use the display this command in interface view to identify these commands.

Field Description Causes of a DOWN link: • Administratively—The interface was shut down by executing the shutdown command. To restore the physical state of the interface, use the undo shutdown command. Cause • Not connected—No physical connection because of absence or failure of network cables. Related commands reset counters interface evb default-manager Use evb default-manager to specify the default VSI manager. Use undo evb default-manager to restore the default.

Use undo evb enable to disable EVB on an interface. Syntax evb enable undo evb enable Default EVB is disabled on an interface.
Related commands • evb s-channel • qinq enable (see Layer 2—LAN Switching) evb mac-learning forbidden Use evb mac-learning forbidden to disable the MAC address learning function for an S-channel. Use undo evb mac-learning forbidden to enable the MAC address learning function for an S-channel. Syntax evb mac-learning forbidden undo evb mac-learning forbidden Default The MAC address learning function for an S-channel is enabled.
Syntax evb reflective-relay undo evb reflective-relay Default The RR mode for an S-channel is disabled. Views S-channel interface view, S-channel aggregate interface view Predefined user roles network-admin mdc-admin Usage guidelines EVB TLVs exchanged through LLDP allow an EVB station and EVB bridge to negotiate the use of reflective relay (RR).
mdc-admin Parameters channel-id: Specifies an S-channel ID (SCID) in the range of 2 to 167. 0 is the reserved SCID, and 1 is the default SCID. svlan-id: Specifies an S-VLAN ID (SVID) in the range of 2 to 4094. 1 is the SVID for the default S-channel. Usage guidelines An S-channel interface is associated with the S-channel that is created on a Layer 2 Ethernet interface. An S-channel aggregate interface is associated with the S-channel that is created on a Layer 2 aggregate interface.
Default The VDP keepalive exponent is 20. Views Layer 2 Ethernet interface view, Layer 2 aggregate interface view Predefined user roles network-admin mdc-admin Parameters value: Specifies a VDP keepalive exponent in the range of 14 to 31. Usage guidelines The value for VDP keepalive time is expressed by the following equation: VDP keepalive time (seconds) = 1.5 × [ 2VDP keepalive + (2 × ECP maximum retransmission time + 1) × 2ECP ] × 10—5 retransmission For detailed values, see Table 7.
VDP keepalive exponent Calculated value (seconds) Result value (seconds) 31 21479.424 21480 Examples # Configure the VDP keepalive exponent on Ten-GigabitEthernet 1/0/1 as 23. system-view [Sysname] interface ten-gigabitethernet 1/0/1 [Sysname-Ten-GigabitEthernet1/0/1] evb vdp timer keepalive exponent 23 # Configure the VDP keepalive exponent on Bridge-Aggregation 1 as 23.

mdc-admin Parameters vsi-local-id: Specifies a VSI local ID in the range of 0 to 1023. association: Specifies the association property. On a VSI with the association property, all filters immediately take effect. pre-association: Specifies the pre-association property. On a VSI with the pre-association property, VLAN filters take effect, but filters are not effective.
Default No VSI or VSI aggregate interface is activated. Views VSI view, VSI aggregate interface view Predefined user roles network-admin mdc-admin Usage guidelines Configurations such as traffic monitoring on a VSI or VSI aggregate interface take effect only after the VSI or VSI aggregate interface is activated. When a VSI or VSI aggregate interface is not activated, only configure filters on the VSI or VSI aggregate interface.
Parameters group group-id: Specifies a group ID that classifies VLAN IDs, in the range of 1 to 4094. When the number of VLANs exceeds 4094, the group ID and VLAN ID together identify a VLAN. vlan vlan-id: Specifies the VLAN ID in the range of 1 to 4094. The VLAN must exist. mac mac-address: Specifies the MAC address, which must be a valid unicast MAC address. Usage guidelines The EVB bridge uses a VSI filter to identify VSI traffic for a VM. Filters are usually assigned by a VSI manager.
• When a filter configured on a VSI aggregate interface contains information about a VLAN, you must not configure the filter on the same VSI aggregate interface again or on other VSI aggregate interfaces of the S-channel aggregate interface. If you do, an error message appears. • Activate a VSI aggregate interface after configuring a VSI filter, and deactivate a VSI aggregate interface before removing a VSI filter. Examples # Configure a VSI filter for VLAN 1 on VSI S-Channel 1/0/1:10.1.
