i have just configured two of my new switches... one being a 4507 and the other a 4506. i have configured them to be layer 2 only (no ip routing) and have set up the 2 vlans that i need routed. anyway, i just want to test connectivity between the two... however, i'm unable to get an up/up on the ports connecting the two switches. i have verified there's no 'shutdown' statement and that the settings are all correct. what have i left out? why can't i sync up the two?
so, i've narrowed it down. the 4507 appears to be fine - i've tested it going to another 4506. the problem seems to be on the 4506. for some reason it show's every interface (including the VLANS) as DOWN - DOWN;whereas every other switch is UP - DOWN on all non-connected interfaces. what would cause the "DOWN - DOWN"?
