[c-nsp] strange vlan issue

[Lee Starnes]

Hi All,

I'm really puzzled by a switch that has stopped working on one vlan only.
This switch has vlans 1 and 2. vlan 1 no longer will pass traffic. I can't
even ping out to it's gateway from the switch, but you can ping the switch
from it's gateway. A show cdp nei shows what it is connected to.

I have replaced the cable and switched to different ports with no luck. I
have never seen an issue where a switch will just stop passing traffic on 1
vlan. We replaced the switch and all is fine, so just want to know if
someone else has seen this issue before.

The switch is a 2950. It has been in service and running flawlessly with the
same config since November of 2002.

Thanks,

Lee
