Usage guidelines

For an S-channel with the 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.

For information about S-channel bundle interfaces, see Layer 2—LAN Switching Configuration Guide.
