Loopbacks on the Cisco (Cerent) 15454

Hardware: E100 FastEthernet cards.

Problem: When placing a physical loopback on the E100 card (Loopplug) the traffic is dropped regardless of Unicast, Multicast or Broadcast traffic.

Observations: Circuit works fine when extended to customer prem equipment. Circuit is Private Line.

We have developed a work around to use a head to head configuration.

It is obvious that the TX and RX MAC match is what is causing this, however, I would like to know is this a problem that is general or is resolved via a software upgrade?

Any ideas and thoughts are welcome.
