[c-nsp] Management interface on 2950T-24 appears to be dead

hi,

had 2 similar issues with a 2950 and a 2960 recently.
in one case, no console access but switch passing
user traffic fine, in the other case, console
access but still no mgmt access out/in.  that second
one we could clearly see the the mgmt VLAN was just 'dead'
on the switch... a reboot out of hours and it was happy back 
to life. keeping an eye on both devices but sometimes
these crazy things seem to happen
