Here's the situation...
I have a 2610xm router I'm trying to connect to a 2950 switch.
If I connect the 2950 to the router, I do not get a link.
I have tried a known-good straight through cable, and a known-good cross-over.
I have tried various combinations of speed and duplex settings on the router and switch.
I tried disabling spanning-tree portfast on the uplink interface.
I have even tried to upgrade the OS on the router. Still, no link.
I didn't have time to upgrade the OS on the switch, but its worth a shot.
Neither the switch or the router display any errors.
The Gotcha is... if I use the same cables I tried before to connect the router to a D-Link unmanaged 24-port gig switch, I get a link. If i connect the D-link to the same port on the 2950 that I tried to connect the router, I get a link. It doesn't matter if I use the straight through from the router to the d-link or the d-link to the 2950 or the cross-over. I always get a link.
So I ask...
Why won't the 2950 talk to the 2610?
Router: Version 12.4(18) I upgraded from 12.3
Switch: Version 12.1(22)EA2
attached are the router and switch configs.
