Ring Mapping on the APM When Trunks Are Configured

Mismatch Resolution does not run when APM trunks are enabled,

which may result in an incorrect ring map. When trunks are enabled,

the number of entries reported on the APM is the number of ports that

have phantom. Although only the active ports are listed, there may be

a mismatch in the port to station mapping when fan-out or MAC-less

devices are present.

When a fanout or MAC-less device is attached to an APM with trunks

enabled, the address map information may be inaccurate for ports

below the fanout or MAC-less device. The address map information for

the other modules on the same network is accurate. If you use fanout

or MAC-less devices on an APM with trunks enabled, 3Com

recommends that you insert the fanout and MAC-less device at the

highest numbered active port.
