VTP Pruning on 6509 server ----> 3750 client

I have a 6509 that is setup as a VTP server and my 3750 is a client. The 3750 is curently only using VLAN90 for the management interface and that interface is up/up. When I type "show interface trunk" on the 6509 side I only see VLAN1 as "Vlans in spanning tree forwarding state and not pruned". It would seem to me that I would see VLAN90 in the same catagory under "show interface trunk".

Configure a port in the 3750 as access-port for Vlan90, plug a workstation - does the behavior change?

Re: VTP Pruning on 6509 server ----> 3750 client

Don't know could have something to do with the core running vtp version 2 and the 3750 is running vtp version one . Is the native vlaN matched on both sides of the trunk ?
