  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?

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.

Hi Guys,
Following doc states that the 4948 supports 4096 vlans:
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
