Switch Catalyst Problem

Alhaji265

I received another Catalyst Switch 2900 XL due to the other one same model showing amber lights on its ports. From ports 25 to 48 on my current switch, the green lights on not displaying and I can't activate any ports, whenever I enter the no shutdown command:

00:09:24: %LINK-3-UPDOWN: Interface FastEthernet0/27, changed state to up
00:09:24: %LINK-3-UPDOWN: Interface FastEthernet0/27, changed state to down

Could this be because VLAN1 status is up when I run show ip interface brief? Any ideas? Thanks

So have you plugged anything in? The port won't stay up if there's nothing plugged into it.

Yes, from my router.

Ok, is the router's ethernet port enabled as well?

Yes, I forgot to mention that I am using a console port for the switch.

So router's fa0/0 is enabled... and you're plugged into sw fa0/27... should come right up. Post your intf configs on both devices. Also, have you wiped this sucker clean, like deleting the vlan.dat, etc?

No, I haven't but when I entered no vlan 1, it stated A default VLAN may not be deleted and it looks like all my ports are in vlan 1 by default after I ran show vlan brief.

Somnipotent

you can't delete vlan 1...
