EVB commands
The S6800 switch series and S6860 switch series support EVB. However, EVB is not supported in an IRF 3.1 system.
The S6820 switch series and S6861 switch series do not support EVB.
EVB requires a license to run on the device. For information about obtaining a license, see Fundamentals Configuration Guide.

Use undo evb default-manager to restore the default.
Syntax
evb default-manager { { ip ipv4-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 ipv4-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 to 192.168.100.20 for the default VSI manager.
<Sysname> system-view
[Sysname] evb default-manager ip 192.168.100.20
evb enable

Usage guidelines
Do not enable EVB on a member port of an aggregation group, or add a member port with EVB enabled into an aggregation group.
Restore all default settings for an interface by using the default command 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.
Except for the LLDP and VLAN settings described in EVB Configuration Guide, do not configure other settings or enable any other Layer 2 protocols 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 Ten-GigabitEthernet 1/0/1.
<Sysname> system-view

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 bridge supports the RR mode, when the EVB station requests the use of 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.
Examples
# Enable the RR mode on S-Channel 1/0/1:10.

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.
Views

Predefined user roles
network-admin
Parameters
channel-id: Specifies an S-channel ID (SCID) in the range of 2 to 167. Value of 0 is the reserved SCID, and value of 1 is the default SCID.
svlan-id: Specifies an S-VLAN ID (SVID) in the range of 2 to 4094. Value of 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 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 you create an S-channel that has the same number as an automatically created S-channel, the (SCID, SVID) pair configuration for the automatically created S-channel takes precedence over the (SCID, SVID) pair configuration for the manually created S-channel.
Creating an S-channel also creates an S-channel interface or S-channel aggregate interface. Removing an S-channel also removes the S-channel interface or S-channel aggregate interface. The S-channel interface or S-channel aggregate interface associated with a manually created S-channel operates in access mode. The S-channel interface or S-channel aggregate interface associated with an automatically created S-channel operates in trunk mode.
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.
When you create an S-channel, follow these restrictions and guidelines:
· Create an S-channel on an interface with EVB enabled.
· When you manually create an S-channel, do not use the SCID or SVID being used by any other S-channels.
· To manually create or remove an 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 8.
Table 8 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 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.

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 immediately, but <VLAN, MAC> filters are not effective until the interface uses the association property.
Usage guidelines
A VSI interface is a subinterface of an S-channel interface, and a VSI aggregate interface is a subinterface of an S-channel aggregate interface.
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.
Removing an S-channel also removes all its VSI interfaces and VSI aggregate interfaces.
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 using the interface command.

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, a group ID and a VLAN ID together identify a VLAN.
vlan vlan-id: Specifies a VLAN ID in the range of 1 to 4094. The VLAN must exist.
mac mac-address: Specifies a 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.
Before configuring a VSI filter, make sure the S-channel interface or the S-channel aggregate interface to which the VSI interface or VSI aggregate interface belongs operates in trunk mode.
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.
When you configure a VSI filter on a VSI interface, follow these restrictions and guidelines:
· 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.
When you configure a VSI filter on a VSI aggregate interface, follow these restrictions and guidelines:
· 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.
