Try and create new vlan:

(config)#vlan 300
(config-vlan)#name test
(config-vlan)#exi
Proposed configuration exceeds the limit of 255 VLANs that can be supported on this platform. Reduce the number of VLANs proposed to be within this limit.APPLY VLAN changes failed.

Anyone seen this before? (I've upgraded IOS to latest, but still have the issue?)
