Usage guidelines
• 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.

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 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.
