Hello I have a strange problem.
I have a C3620 with a NM-4E module and a Cisco 2950T-24 switch.
If I connect a port of the NM-4E to a port of the catalyst, the led lights up, the port goes on UP state but no packets get through.
If I put a port of the NM4E to any different switch, it works, pings etc.
I tried to set manually full duplex operation both on the sw and the router (to achieve 10/full) but it doesn't work.
I didn't have any problems linking a C2611 in 10/full to a Catalyst 2912XL (forced 10/full) achieving without any problems (on the counters) 10/full.
Why It doesn't work here on the 2950T24?
thank you
