2950T:Copper Gig, Crossover GigabitEthernet0/2 is up, line protocol is down
For years I have connected two Catalysts via a cross-over cable. Today I have a new 2950T (copper gigabit ports) that don't get link with a cross-over cable. If I move the crossover between two fastethernets I get link.
What am I missing? I tried a no-shut, I tried hardcoding speed 1000, I upgraded to latest IOS, I called TAC, etc...
Both sides show the same/below;
