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 127 characters.
port port-number: Specifies the port number of the default VSI manager, in the range of 0 to 65535. The default port number is 8080.
local-server: Specifies the device as the default VSI manager.
Usage guidelines
When the bridge receives a VDP packet (except for a De-Associate packet) from a station, it contacts the VSI manager specified in the VDP packet to get VSI interface resources and policies for the station.
The VSI manager ID TLV in a VDP packet carries the VSI manager's IP address. If the value for the TLV is 0, the bridge communicates with the default VSI manager specified by this command.
Examples
# Set the IPv4 address of the default VSI manager to 192.168.100.20.

Usage guidelines
EVB is applicable only to interfaces on the following interface modules:
· EC interface modules.
· SC interface modules:
¡ LSQM2GP44TSSC0.
¡ LSQM2GP24TSSC0.
¡ LSQM2GT24PTSSC0.
¡ LSQM2GT24TSSC0.
¡ LSQM2GT48SC0.
¡ LSQM4GV48SC0.
· SF interface modules.
· SG interface modules.
Do not enable EVB on a member port of an aggregation group, or add a member port with EVB enabled into an aggregation group. Otherwise, an error message appears.
Do not enable both EVB and QinQ on the same interface.
Do not create a service instance for an interface enabled with EVB, and vice versa.
Restore all default settings for an interface before enabling EVB on the interface.
A default S-channel is created on an interface after EVB is enabled on the interface, with both SCID and SVID as 1. After an S-channel is created, an S-channel interface or S-channel aggregate interface is created and operates in access mode.
Do not configure VLAN settings or enable any other Layer 2 protocol on an interface with EVB enabled.
Delete all non-default S-channels on an interface before disabling EVB on the interface. The default S-channel is deleted after EVB is disabled.
Examples
# Enable EVB on GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1

Usage guidelines
For an S-channel with the RR mode disabled, do not disable its MAC address learning function. Otherwise, the EVB bridge might fail to forward traffic from VMs on the EVB station.
After you disable the MAC address learning function for an S-channel, packets with an unknown source MAC address are discarded.
The undo evb mac-learning forbidden command and the mac-address mac-learning enable command must be configured together to avoid communication interruption.
Examples
# Disable the MAC address learning function on S-Channel 1/0/1:10.

EVB TLVs exchanged through LLDP allow an EVB station and EVB bridge to negotiate the use of reflective relay (RR). If the EVB bridge supports the RR mode, when the EVB station requests the use of the RR mode, the bridge performs the following tasks:
· Automatically enables the RR mode for the S-channel.
· Adds the corresponding command line to the configuration file.
You can also use this command to manually enable or disable the RR mode for an S-channel.
Examples
# Enable the RR mode on S-Channel 1/0/1:10.
<Sysname> system-view
[Sysname] interface s-channel 1/0/1:10
[Sysname-S-Channel1/0/1:10] evb reflective-relay
# Enable the RR mode on Schannel-Aggregation 1:10.
<Sysname> system-view
[Sysname] interface schannel-aggregation 1:10
[Sysname–Schannel-Aggregation1:10] evb reflective-relay
evb s-channel
Use evb s-channel to create an S-channel on an interface.
Use undo evb s-channel to remove an S-channel on an interface.
Syntax
evb s-channel channel-id [ service-vlan svlan-id ]
undo evb s-channel channel-id
Default
Only an automatically created default S-channel (with both SCID and SVID as 1) exists on an interface with EVB enabled.

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. If you do not specify this argument, the system automatically assigns the minimum SVID that is not used by other S-channels.
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.
· An S-channel is automatically created through CDCP, and the command line corresponding to the action is added to the configuration file on the bridge. You can also manually create an S-channel by using this command. If an (SCID, SVID) pair for an S-channel is created both automatically and manually, the automatically created S-channel takes precedence.
· After an S-channel is created, an S-channel interface or S-channel aggregate interface is generated. Removing an S-channel also removes the S-channel interface or S-channel aggregate interface. A manually created S-channel interface or S-channel aggregate interface operates in access mode. An S-channel interface or S-channel aggregate interface that is automatically created through CDCP operates in trunk mode.
· When you manually create an S-channel, do not use the SCID or SVID being used by any other S-channel. Otherwise, an error message appears.
· Create an S-channel on an interface with EVB enabled. Otherwise, an error message appears.
· To manually create or remove S-channel, disable CDCP that automatically performs these operations.

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 retransmission ] × 10—5
For detailed values, see Table 7.
Table 7 uses 3 and 14 (the defaults) as the ECP maximum retransmission time and the ECP retransmission exponent to calculate the VDP keepalive time. These two variables use the larger values proposed by the station and bridge through EVB TLV.
The network environment and configurations on the EVB bridge and station determine whether to use the defaults or the actual proposed values for the following ECP values:
· ECP maximum retransmission time.
· ECP retransmission exponent.

Parameters
vsi-local-id: Specifies a VSI local ID in the range of 0 to 1023.
association: Specifies the association property. On a VSI interface with the association property, all filters immediately take effect.
pre-association: Specifies the pre-association property. On a VSI interface with the pre-association property, VLAN filters take effect, but <VLAN, MAC> filters are not effective.
Usage guidelines
Removing an S-channel also removes all its VSI interfaces and VSI aggregate interfaces.
A VSI interface or VSI aggregate interface is usually created or deleted by a VSI manager. You can also manually create or delete a VSI interface, or modify its pre-association or association property by executing this command.
If MAC address information is contained in the traffic sent by a VM when you change association to pre-association for a VSI interface or VSI aggregate interface, the following events occur:
· The MAC address is removed from the drive on the EVB bridge.
· The traffic from the VM cannot be forwarded.
When you change pre-association to association for a VSI interface, the EVB bridge sets the VM's MAC address.
After creating a VSI interface or VSI aggregate interface, you can enter VSI interface view or VSI aggregate interface view by executing the interface command.

Usage guidelines
Configurations such as traffic monitoring on a VSI interface or VSI aggregate interface take effect only after the VSI interface or VSI aggregate interface is activated. When a VSI interface or VSI aggregate interface is not activated, do not make any configurations other than filters on either interface. For more information about traffic monitoring, see ACL and QoS Configuration Guide.
Activate a VSI interface or VSI aggregate interface after configuring a VSI filter, and deactivate a VSI interface or VSI aggregate interface before removing a VSI filter.

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 VSI filters to identify VSI traffic. Typically a VSI manager assigns filters. You can use this command to manually create or remove a VSI filter.
A VSI filter contains a set of VID values, MAC addresses, and group ID values. EVB supports the following filter info formats:
· VLAN ID.
· VLAN ID + MAC.
· Group ID + VLAN ID.
· Group ID + VLAN ID + MAC.
When you configure a VSI filter on a VSI interface, follow these guidelines:
· For the VSI filter configuration to take effect, make sure the S-channel interface to which the VSI interface belongs operates in trunk mode.
· When you create a VSI filter, the following interfaces automatically permit the VLAN contained in the VSI filter:
¡ The S-channel interface to which the VSI interface belongs.
¡ The Layer 2 Ethernet interface where the S-channel that is associated with the S-channel interface is created.
· When you delete a VSI filter, the following interfaces automatically deny the VLAN in the filter if the VSI filters on the other VSI interfaces created on the same S-channel interface do not contain the VLAN:
¡ The S-channel interface to which the VSI interface belongs.
¡ The Layer 2 Ethernet interface where the S-channel that is associated with the S-channel interface is created.
· Do not create a VSI filter that contains the same VLAN on the same VSI interface or on other VSI interfaces that belong to the same S-channel interface. If you do so, the system displays an error message.
· Disabling MAC address learning for an S-channel prevents the traffic from the VSI from being forwarded if the VSI filter contains the VLAN to which the traffic belongs.
· Activate a VSI interface after configuring a VSI filter, and deactivate a VSI interface before removing a VSI filter.
When you configure VSI filters on a VSI aggregate interface, follow these guidelines:
· For the VSI filter configuration to take effect, make sure the S-channel aggregate interface to which the VSI aggregate interface belongs operates in trunk mode.
· When you create a VSI filter, the following interfaces automatically permit the VLAN contained in the VSI filter:
¡ The S-channel aggregate interface to which the VSI aggregate interface belongs.
¡ The Layer 2 aggregate interface where the S-channel that is associated with the S-channel aggregate interface is created.
· When you delete a VSI filter, the following interfaces automatically deny the VLAN in the filter if the VSI filters on the other VSI aggregate interfaces created on the same S-channel aggregate interface do not contain the VLAN:
¡ The S-channel aggregate interface to which the VSI aggregate interface belongs.
¡ The Layer 2 aggregate interface where the S-channel that is associated with the S-channel aggregate interface is created.
· Do not create a VSI filter that contains the same VLAN on the same VSI aggregate interface or on other VSI aggregate interfaces that belong to the same S-channel aggregate interface. If you do so, the system displays an error message.
· Activate a VSI aggregate interface after configuring a VSI filter, and deactivate a VSI aggregate interface before removing a VSI filter.
