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

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.
