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.

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

11
Default
EVB is disabled on a port.
Views
Ethernet interface view
Predefined user roles
network-admin
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 Twenty-GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface TwentyGigE 1/0/1
[Sysname-TwentyGigE1/0/1] 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.

12
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.
Examples
# Disable the MAC address learning function for S-channel 1/0/1:10.
<Sysname> system-view

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.
Views

Predefined user roles

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.

13
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
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

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.

# Create an S-channel on Twenty-GigabitEthernet 1/0/1, with the SCID 10 and SVID 5.

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

Parameters
vsi-local-id: Specifies a VSI local ID in the range of 0 to 1023.
association: Specifies the association property. On a VSI with the association property, all filters
immediately take effect.
pre-association: Specifies the pre-association property. On a VSI with the pre-association property,
VLAN filters take effect, but <VLAN, MAC> filters are not effective.

Usage guidelines
•A VSI is usually created or deleted by a VSI manager. You can also manually create or delete a VSI,
or modify its pre-association or association property by executing this command.
•A VSI is a subinterface of an S-channel interface. Removing an S-channel also removes all its VSIs.
•When you change association to pre-association for a VSI, if MAC address information is
contained in the traffic sent by a VM, the MAC address is removed from the drive on the EVB bridge,
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 1and association property.
<Sysname> system-view
[Sysname] interface s-channel 1/0/1:10
[Sysname-S-Channel1/0/1:10] evb vsi 1 association

evb vsi active
Use evb vsi active to activate a VSI.
Use undo evb vsi active to deactivate a VSI.
Syntax

Default
No VSI is activated.

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

# Activate S-channel 1/0/1:10.1.
