2950 not working properly ( don't route and don't forward traffic)

[khaled alodat]

Hi ,

It's a very strange problem, i don't even know how to explain it.

I have a 2951  router  between our company and a customer. every two to three days i keep phasing the same issue . the router will stop forwarding traffic . physically there is nothing wrong with it.

when the traffic is not going  you can ping ssh without any problem , nothing on the syslog server.

I've checked ARP, MAC address for anything , but no luck.

The only thing i can do is to reload the router .

Cisco 2951 : c2951-universalk9-mz.SPA.152-1.T2.bin

Thanks,

Khaled

When the issue occurs and you are able to SSH to the router, what does the routing table show?

#show ip route

This is why I said it's a strange problem. 

The routing table was fine all time, I've checked it.

routing --> fine

mac-add-table--> fine

arp--> fine

I guess it could be a bug, have you tried updating the IOS?
