Hi - also check all your trunk ports and make sure you are specifying only active/valid VLANs individually, by using:
switchport trunk allowed vlan 1,2,101,102,etc. If there are unrestricted trunk ports then again you may have resources tied up for VLANs which have since been removed but it's just not showing them to you.

Hi, 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. I know you are in transparent mode, but interestingly we have some 2960G units which show pruning as 'enabled' even though VTP is off globally: #sh run | inc vtp vtp mode off #sh vtp stat VTP Version capable : 1 to 3 VTP version running : 3 VTP Domain Name : VTP Pruning Mode : Enabled VTP Traps Generation : Disabled Device ID : x.x.x Feature VLAN: -------------- VTP Operating Mode : Off Number of existing VLANs : 42 Number of existing extended VLANs : 0 Maximum VLANs supported locally : 255 Ours are running 15.0(2) Maybe you can also check: sh vlan br | count act sh vlan | count enet Just out of curiosity, cheers!

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?) _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
