EVB commands description Use description to configure a description for an interface. Use undo description to restore the default. Syntax description text undo description Default The default description for an interface is "interface name Interface." For example, the default description for S-channel interface S-channel 1/0/1:10 is S-channel 1/0/1:10 Interface. The default description for VSI S-channel1/0/1:10.1 is S-channel 1/0/1:10.1 Interface.
network-operator Parameters interface interface-type interface-number: Specifies a port by its type and number. If no interface is specified, the command displays CDCP negotiation information for all ports with EVB enabled. Examples # Display CDCP negotiation information for all ports with EVB enabled.
Examples # Display EVB TLV negotiation information for Ten-GigabitEthernet 1/0/1.
Field Description Max ECP retry time Maximum ECP retransmission times in the format: Local negotiation value/Remote negotiation value/Operative value. NA means no value is set on the remote EVB station. ULPPDU retransmission exponent ECP retransmission exponent in the format: Local negotiation value/Remote negotiation value/Operative value. NA means no value is set on the remote EVB station.

Syntax display evb summary Views Any view Predefined user roles network-admin network-operator Examples # Display the EVB summary. display evb summary Default manager ID: 192.168.1.
Parameters verbose: Displays detailed VSI information. Without this keyword, the command displays brief VSI information. interface interface-type interface-number: Specifies a port by its type and number. If no interface is specified, the command displays VSI information for all ports with EVB enabled. Examples # Display brief VSI information for Ten-GigabitEthernet 1/0/1.
Field VSI manager ID Description Address of the VSI manager. NA indicates no VSI manager is specified. VSI filter type: Filter type • VLAN ID. • MAC address/VLAN ID. VSI filters: Filter info • In the format of , meaning the VLAN to which the traffic belongs. • In the format of , meaning the destination MAC for the traffic and the VLAN to which the traffic belongs.

Assume that you have configured a description for the interface as 1234567890123456789012345678901234567890.
The brief information of interface(s) under bridge mode: Link: ADM - administratively down; Stby - standby Speed or Duplex: (a)/A - auto; H - half; F - full Type: A - access; T - trunk; H - hybrid Interface Link Speed Duplex Type PVID Description SCH1/0/1:10.1 UP -- -- -- -- 12345678901234567890123456789 01234567890 Table 6 Command output Field Description Interface status: • Administratively DOWN—The interface is administratively down.
Syntax evb default-manager { { ip ip-address | ipv6 ipv6-address | name name } [ port port-number ] | local-server } undo evb default-manager Default The default VSI manager is not specified. Views System view Predefined user roles network-admin Parameters ip ip-address: Specifies the IPv4 address of the default VSI manager. ipv6 ipv6-address: Specifies the IPv6 address of the default VSI manager. name name: Specifies the name of the default VSI manager, a case-insensitive string of 1 to 255 characters.
Predefined user roles network-admin Usage guidelines • Do not enable EVB on a member port of an aggregation group. • Restore all default settings for a port before enabling EVB on the port. • A default S-channel is automatically created on a port after EVB is enabled on the port, with both SCID and SVID as 1. After an S-channel is created, an S-channel interface is automatically created and operates in access mode.
Examples # Disable the MAC address learning function for S-channel 1/0/1:10. system-view [Sysname] interface s-channel 1/0/1:10 [Sysname-S-Channel1/0/1:10] evb mac-learning forbidden Related commands evb reflective-relay evb reflective-relay Use evb reflective-relay to enable the RR mode for an S-channel. Use undo evb reflective-relay to disable the RR mode for an S-channel. Syntax evb reflective-relay undo evb reflective-relay Default The RR mode for an S-channel is disabled.
Default Only an automatically created default S-channel, with both SCID and SVID as 1, exists on a port with EVB enabled. Views Layer 2 Ethernet interface view Predefined user roles network-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.
Default The VDP keepalive exponent is 20. Views Layer 2 Ethernet interface view Predefined user roles network-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.
Examples # Configure the VDP keepalive exponent for 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 evb vdp timer resource-wait-delay exponent Use evb vdp timer resource-wait-delay exponent to configure a VDP resource-wait-delay exponent. Use undo evb vdp timer resource-wait-delay exponent to restore the default.

and the traffic from the VM cannot be forwarded. When you change pre-association to association for a VSI, the EVB bridge sets the VM's MAC address. • After creating a VSI, you can enter VSI view by executing the interface s-channel command. Examples # Create a VSI on S-channel 1/0/1:10, with VSI local ID 1 and association property.
evb vsi filter Use evb vsi filter to configure a VSI filter. Use undo evb vsi filter to remove a VSI filter. Syntax evb vsi filter vlan vlan-id [ mac mac-address ] undo evb vsi filter [ vlan vlan-id [ mac mac-address ] ] Default No VSI filter exists. Views VSI view Predefined user roles network-admin Parameters 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.
Syntax interface s-channel { interface-number:channel-id | interface-number:channel-id.vsi-local-id } Views System view Predefined user roles network-admin Parameters interface-number:channel-id: Specifies an S-channel interface. The interface-number argument specifies the physical port where the S-channel resides. The channel-id argument specifies the ID of the S-channel, and its value range is the set of all existing S-channel numbers. interface-number:channel-id.vsi-local-id: Specifies a VSI.
Usage guidelines • To collect traffic statistics for an S-channel interface or a VSI in a certain period, use this command to clear existing statistics for the interface. • If no parameters are specified, the command clears statistics for all interfaces. • If only the s-channel keyword is specified, the command clears statistics for all created S-channel interfaces and VSIs. Examples # Clear statistics for S-channel interface S-channel 1/0/1:10.
