Are you running vtp v3? 

Check the VTP Version Running line in sh vtp status.

  Thanks for the clarification Tony - What is the command to show how many vlans the switch supports?   "sh vlan summary" shows how many are used, but not how many are supported/available?

Hi,



That is the number of VLAN's supported by VTP (VLAN trunking protocol), not the switch itself.



===

VTP version 1 and version 2 support only

normal-range VLANs (VLAN IDs 1 to 1005). In these versions, the switch

must be in VTP transparent mode when you create VLAN IDs from 1006 to

4094. Cisco IOS Release 12.2(52)SE and later support VTP version 3. VTP

version 3 supports the entire VLAN range (VLANs 1 to 4094). Extended

range VLANs (VLANs 1006 to 4094) are supported only in VTP version 3.

You cannot convert from VTP version 3 to VTP version 2 if extended VLANs

 are configured in the domain.



===



regards,

Tony.

Hi Guys,





Following doc states that the 4948 supports 4096 vlans:





http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps6021/product_data_sheet0900aecd8017a72e.html








But if I run "sh vtp status" on one of our 4948's it states it only supports 1005 vlans?





Feature VLAN:

--------------

VTP Operating Mode                : Transparent

Maximum VLANs supported locally   : 1005

   Cheers.
