the learning interface facing subscribers. Traffic coming into this interface is
forwarded to the uplink regardless of the destination MAC address.
Broadcasts and unicasts (known and unknown) will be sent out the default
interface, which is the uplink bridge for the VLAN.
Packets entering the system on this interface have their source MAC
addresses learned and associated with this interface. Because this interface is
not a default, it is required to learn MAC addresses, so that frames from the
network that come in on the uplink bridge can be sent to the correct downlink
bridge.
Configure the EtherXtend with uplink and downlink bridges when the uplink
bridge is the path upstream to the network, and the downlink bridge is the
learning interface facing subscribers as shown in
