evb default-manager
Use evb default-manager to specify the default VSI manager.
Use undo evb default-manager to restore the default.

10
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

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.
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 other than a De-Associate packet from a station, it contacts the
VSI manager specified in the VDP packet to get VSI 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
all-zero, 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.
<Sysname> system-view
[Sysname] evb default-manager ip 192.168.100.20
evb enable
Use evb enable to enable EVB on a port.
Use undo evb enable to disable EVB on a port.
Syntax
evb enable
undo evb enable
Default
EVB is disabled on a port.

Usage guidelines
•After you enable EVB on the bridge port, the device cannot forward the data received from the port
at Layer 3.
•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.
•Do not configure VLAN settings or enable any other Layer 2 protocol on a port with EVB enabled.
•Delete all non-default S-channels on a port before disabling EVB on the port. The default S-channel
is automatically deleted when EVB is disabled.
•Do not enable both EVB and QinQ on the same port.
Examples
# Enable EVB on Ten-GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] evb enable

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.

Usage guidelines
•For an S-channel with RR mode disabled, do not disable its MAC address learning function.
Otherwise, the EVB bridge might fail to forward the 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.

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.

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 the use of RR mode and the EVB bridge supports RR mode, the
bridge automatically enables RR mode for the S-channel and 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
evb s-channel
Use evb s-channel to create an S-channel on a port.
Use undo evb s-channel to remove an S-channel on a port.
Syntax
evb s-channel channel-id service-vlan svlan-id
undo evb s-channel channel-id

13
Default
Only an automatically created default S-channel, with both SCID and SVID as 1, exists on a port with EVB
enabled.

Parameters
channel-id: Specifies an S-channel ID (SCID) in the range of 2 to 167. 0is the reserved SCID, and 1is the
default SCID.
svlan-id: Specifies an S-VLAN ID (SVID) in the range of 2 to 4094. 1is the SVID for the default S-channel.
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 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 is automatically generated. Removing an
S-channel also removes the corresponding S-channel interface. A manually created S-channel
interface operates in access mode, and an S-channel 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 is displayed.
•Create an S-channel on a port with EVB enabled. Otherwise, an error is displayed.
•To manually create or remove S-channel, disable CDCP to automatically perform these operations.
Examples
# Create an S-channel on Ten-GigabitEthernet 1/0/1, with the SCID 10 and SVID 5.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
