Changing the Management IP on WS-C2950t-24

[keith.magyar1]

I need this switch in vlan 119 for management. Can someone tell me why when I pass the no shut command on int vlan 119 that I lose the switch entirely? It is uplinked off of a cisco sg300

The C2950 can't have more than one vlan interface administratively up at once, so when you "no shut" interface vlan 119 it will shut interface vlan 11.

Either you reconfigure it via serial console, or you can try to assign an IP address to interface vlan 119, then "no shut" it, then access the C2950 from a computer in the same subnet in vlan 119 and change its default gateway to match the new management subnet...

Hi,

It could be a bug, This device is too old and probably there are no new images to upgrade it.
