I have 2 cisco c2950 switches, I have 2 problems:
1- I can't create more than 1001 vlan..(I have configured the both switches with vtp transparent mode).
2- when I issue the command (sh vtp status), I noticed that vlans supported locally 64 & number of existing vlans are 63.
(a)does that means Spantree won't operate after vlan number 64. If so? how would I solve this issue?
(b) what is the possiblity that allows me to assign more than 1001 (Extended vlans) in cisco c2950 series?

Hi,
The box that you have is a 2950 with SMI, standard image and that doesnot have the features you are looking for.

Hi Friend,
Catalyst 2950 switches that run the standard software image (SI) support 64 VLANs; Catalyst 2950 and Catalyst 2955 switches that run the enhanced software image (EI) support 250 VLANs. Refer to the release notes for the list of switches that support each image. VLANs are identified with a number from 1 to 4094 when the EI is installed and 1 to 1005 when the SI is installed. 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.

Hi Friend,
AFAIK 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.
The switch supports per-VLAN spanning-tree plus (PVST+) and rapid PVST+ with a maximum of 128 spanning-tree instances. One spanning-tree instance is allowed per VLAN.
