5.3. bShell Troubleshooting
Maintenance Shell commands should only be used by Alcatel-Lucent personnel or under the direction of Alcatel-
Lucent. Misuse or failure to follow procedures that use Maintenance Shell commands in this guide correctly can
cause lengthy network down time and/or permanent damage to hardware.
If a problem is specific to a NI and the MAC address is not being learned by the switch, the first step is to
verify from the the NI that the MAC address has been learned. There is a possibility that the NI has learned the
MAC but CMM is not reporting that MAC because of lost IPC messages between the CMM and NI.
The “l2 show” command will dump all of the MAC addresses. Check the “show mac-learning summary”
command to confirm how many mac-addresses are present befoare using the “l2 show” command.
