[c-nsp] Overruns

[Mohammad Khalil]

hi all 

i have 2 cisco 7606 routers connected to ASN GW for wimax traffic
we had a problem with overruns on the port channels 
we connected 5 cables from the ASN to both routers and configured port channels for VLAN and the same setup for another vlan
one vlan is for communcations with RASs and one to transport the traffic for into the core cloud
anyway we upgraded the IOS version on the routers thinking thats might solve the issue but still 
please find below

CR1.KJ-Building#sh int po10 | inc over
     1 input errors, 1 CRC, 0 frame, 72395 overrun, 0 ignored
CR1.KJ-Building#sh int po20 | inc over
