Re: Cat6509 with "AAL5-3-INTERNAL_ERROR" error message
Regarding to Multilayer Switch Module and Cisco IOS 12.0, I've found next information about such error message:
The MSM supports up to 2,500 routes and 25 Enhanced Interior Gateway Routing Protocol (EIGRP) neighbors. Reducing the number of neighbors allows you to increase the number of routes and decreasing the number of routes allows you to increase the number of neighbors. Using EIGRP with larger numbers of routes and neighbors might cause high CPU utilization. High CPU utilization may cause the MSM to lose routes and EIGRP neighbors. Specific problems related to large numbers of routes and neighbors are as follows:
If the number of neighbors goes beyond 25 while keeping the number of routing entries the same (2500), the following message might display:
%AAL5-3-INTERNAL_ERROR: No more big aal5 pkts
Just check if you have such number of neighbors and routes.
