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.
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
Follow these guidelines when you enable or disable EVB on an interface:
· 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.
· 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.
· Do not enable both EVB and QinQ on the same interface.

Usage guidelines
EVB TLVs exchanged through LLDP allow an EVB station and EVB bridge to negotiate the use of reflective relay (RR). If the EVB station requests to use the RR mode and the EVB bridge supports the RR mode, the bridge performs the following operations:
· 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

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, and an S-channel interface or S-channel aggregate interface that is automatically created through CDCP operates in trunk mode.
· Create an S-channel on an interface with EVB enabled. Otherwise, an error message appears.
· 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.
· 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 16 (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 settings 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.

Predefined user roles
network-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 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
A VSI interface is an interface created on an S-channel interface through this command, and it is a subinterface of the S-channel interface. A VSI aggregate interface is created on an S-channel aggregate interface, and it is a subinterface of the S-channel aggregate interface. 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
Settings 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 settings other than filters on the 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 a VSI filter to identify VSI traffic for a VM. Filters are usually assigned by a VSI manager. You can also manually create or remove a VSI filter by executing this command.
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 VSI filters on a VSI interface, follow these guidelines:
· Before you configure a VSI filter on a VSI interface, make sure the S-channel interface to which the VSI interface belongs operates in trunk mode. Otherwise, the VSI filter configuration fails.
· After you configure a VSI filter on a VSI interface, an S-channel interface automatically permits the VLAN that is configured in the VSI filter for the subordinate VSI interface. The same rule takes effect on Layer 2 interfaces associated with S-channels.
· When you delete a VSI filter that contains information about a VLAN on a VSI interface, the other VSI filters on all VSI interfaces of an S-channel interface might not contain the VLAN. If they do not, the S-channel interface automatically denies traffic from the VLAN that is configured on the VSI filter. The same rule takes effect on Layer 2 interfaces associated with S-channels.
· When a filter configured on a VSI interface contains information about a VLAN, you must not configure the filter on the same VSI interface again or on other VSI interfaces of the S-channel interface. If you do, an error message appears.
· If the VSI filter is a set of VID values, and the MAC address learning function for the corresponding S-channel is disabled, traffic for the VSI cannot be forwarded.
· 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:
· Before you configure a VSI filter on a VSI aggregate interface, make sure the S-channel aggregate interface to which the VSI aggregate interface belongs operates in trunk mode. Otherwise, the VSI filter configuration fails.
· After you configure a VSI filter on a VSI aggregate interface, an S-channel aggregate interface automatically permits the VLAN that is configured in the VSI filter for the subordinate VSI aggregate interface. The same rule takes effect on Layer 2 aggregate interfaces associated with S-channels.
· When you delete a VSI filter that contains information about a VLAN on a VSI aggregate interface, the other VSI filters on all VSI aggregate interfaces of an S-channel aggregate interface might not contain the VLAN. If they do not, the S-channel aggregate interface automatically denies traffic from the VLAN that is configured on the VSI filter. The same rule takes effect on Layer 2 aggregate interfaces associated with S-channels.
· 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.
