[c-nsp] vlan limit hit...but havent?

[CiscoNSP_list CiscoNSP_list]

thanks Robert - vtp pruning is not enabled (And switch was reloaded recently when IOS was updated)

"sh vlan br | count act"  reports 254 though:
Number of lines which match regexp = 254

Any idea where the switch is getting the existing vlan number of 220?
Number of existing VLANs          : 220


Cheers.

> Just an idea, but have you tried "vtp pruning" in the config? If it is a bug then maybe it's a result of not clearing VLANs which were previously present but have been removed or re-numbered. Perhaps they are stuck in the VTP DB/cache pending a reload or similar event.
