EtherXtend CO and CPE mode bridge scenarios
EtherXtends can be configured in either CO mode or CPE mode with either
Transparent LAN Services (TLS) or uplink/downlink bridges. To enable
bridged interfaces on the EtherXtend, different bridge types can be configured
on the device depending on the mode of operation.

Bridges on EtherXtend CPE mode
When the EtherXtend is configured in CPE mode, the WAN traffic connects
to a MALC EFM card through a bonded connection and the LAN traffic
connects to subscribers. In this mode, the EtherXtend WAN and LAN
interfaces can use either TLS bridging or uplink/downlink bridging.
Configure TLS bridges
TLS bridges learn MAC addresses and forward packets to learned
destinations. Broadcasts and unknown unicasts are flooded out all interfaces
except the ingress interface. Packets entering the system on TLS interface
have their source MAC addresses learned and associated with the interface so
that frames from the network that come in on other TLS bridges in the VLAN
can be sent to the correct interface. A TLS bridge is used with only other TLS
bridges. This should not be used with any asymmetrical bridges. TLS bridges
must be configured on both the WAN and the LAN ports on the EtherXtend as
