Hello
Can some ones please help me?
I have a 4507R+E ver 15.0. two 48-port line cards two super-engine cards, and we had some 10 like PCs connected over two cards, all worked fine before. But no one really used those PCs after setup, so don't know when, but today we found all those PC conneccted ports are down-down. We tried connecting a laptop(it worked fine with other switches) on the 4507, tried different ports and cables, tried auto-negotiation and forced speed and duplex, tried shut and none-shut ports, but just cannot get any switch ports up. switch ports stayed down-down. The config on ports just one line 'switchport access vlan 1'.
Well there is only one exception, during all the time, port1/1 which is connecting to a Cisco ASA is always up. Seems the 4507 just cannot connect to any computers. Even tried soft reload the switch, didn't fix the problem.
what can I do now? open a case with TAC? anything eles I can do?
Thanks a lot.
