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
.
<Sysname> system-view
[Sysname] evb default-manager ip 192.168.100.20
evb enable
Use
evb enable
to enable EVB on an interface.
Use
undo evb enabl
e to disable EVB on an interface.
Syntax
evb enable
undo evb enable
Default
EVB is disabled on an interface.

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.
•
Do not create a service instance for an interface enabled with EVB, and vice versa.
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
# Enable EVB on Bridge-Aggregation 1.
