Hi
You can't configure extended vlans from vlan database config mode.
From config mode
JPR-MPL-COR-SWH-78(config)# vlan 3000
=============================================
Configuring Extended-Range VLANs
When the switch is in VTP transparent mode (VTP disabled), you can create extended-range VLANs (in the range 1006 to 4094 for any switch port commands that allow VLAN IDs). Enter the vlan vlan-id global configuration command to access config-vlan mode and to configure extended-range VLANs. The VLAN database configuration mode (that you access by entering the vlan database privileged EXEC command) does not support the extended range.

Hi
Yes it will as long as you are in VTP transparent mode which you are from your vtp status output.

Ya
but it shows Maximum VLANs supported locally : 1005
How can I go beyond this

** Edit - excerpt from 3550 Cisco config doc
=============================================
Supported VLANs
The Catalyst 3550 switch supports 1005 VLANs in VTP client, server, and transparent modes. VLANs are identified with a number from 1 to 4094. VLAN IDs 1002 through 1005 are reserved for Token Ring and FDDI VLANs. VTP only learns normal-range VLANs, with VLAN IDs 1 to 1005; VLAN IDs greater than 1005 are extended-range VLANs and are not stored in the VLAN database. The switch must be in VTP transparent mode when you create VLAN IDs from 1006 to 4094.
=============================================
So "VTP only learns normal-range VLANs". That is why you see the figure 1005 in sh vtp status but the switch will support extended vlans.

Hello Jon,
I understood that we can only do the extended VLAN configuration in transparent mode,if we are using vtp version 2.
But is there any specific reason that we cant configure it in Server mode?
Thanks in advance!!!
