Check the debug output for the interface in question. Notice in the example the interface ATM 8/0/0
old_state field transitions from ALLOCATED to new_state UNBORN.
Port Stuck Message
The following console error message might appear if one or more of the Ethernet ports on the Catalyst
8500 CSR or MSR experiences a port stuck condition:
%AAL5-3-INTERNAL_ERROR: aal5send: mmc_queuecell failed...
If the port stuck condition continues for an extended period of time with a significant traffic load, it
might cause the console to become almost completely useless.
