Known Affected Releases

6.2(10)S7 6.2(8)E2

Description (partial)

Symptom:

Converted one port to L2 Port-Channel and create 1-3967 Vlans associated with this port Channel. This is Invalid config because no way to fit that many TCAM entries. We expect proper reject on that operation

But we get service not responding.
