Extended VLAN range 1

[dvtestguy]

I have a 6506 -- (Server) -- VTP -- (Client) -- 4948, and have used VLAN 1-999, and Cisco uses 1000-1024. I'd like to be able to use VLAN ranges 1025 and above, but looks like VTP/ISL won't support extended VLAN ranges?

Any ideas?

I won't ask how you have used 1000 vlans off one vtp server up . You must have a very extended trunked network to have to need this many vlans. No you can not used extended vlans in a vtp environment . You should probably think about breaking up your vtp domain into smaller ones if this is a problem . Below is some info from cisco.

Extended-Range VLAN Configuration Guidelines

This section describes the guidelines for creating extended-range VLANs 1025-4094:

•You can only create Ethernet-type VLANs in the extended range.

•You must enable MAC address reduction in order to use extended-range VLANs.

•You can only create and delete extended-range VLANs from the CLI or SNMP.

•You cannot use VTP to manage these VLANs; they must be statically configured on each switch.

•You cannot use extended-range VLANs if you have dot1q-to-isl mappings.

•You can configure private VLAN parameters and RSPAN for extended-range VLANs; however, all other parameters for extended-range VLANs use the system defaults only.

•The switch may allocate a block of VLANs from the extended range for internal purposes; for example, the switch may allocate VLANs for routed ports or FlexWAN modules. The block of VLANs is always allocated starting from VLAN 1025. If you have any VLANs within the range that is required by the FlexWAN module, all of the VLANs that are required will not be allocated, because VLANs are never allocated from the user's VLAN area.
