I am not sure if this is a bug
but everytime I enable
ip routing the switch Locks up on me
and I have to reboot it to get it back up.
Here is the model type and
IOS I tried it on both
with same results
In your current configuration, did you use "ip default-gateway x.x.x.x" to configure the default gateway? If yes, after you enable "ip routing", the switch won't know it's default gateway any more. That's why you could not access the switch.
If possible, try to add "ip route 0.0.0.0 0.0.0.0 " first before you enable "ip routing".
If not possible, you have to telnet/SSH to the switch from its default gateway so that you can still have access to the switch after you enable "ip routing".
