Not seeing all VLANS

Hi I have several switches, a 3750 Catalyst, a 3650 and 2 2960's The 2 2960's are not seeing all the VLANs and I can't work out why All switches are using VLAN1 and all are in the same subnet

10.200.200.0

Here is the config bits

3750 sh vtp status VTP Version : 2 Configuration Revision : 2 Maximum VLANs supported locally : 1005 Number of existing VLANs : 10 VTP Operating Mode : Server VTP Domain Name : AFF VTP Pruning Mode : Enabled VTP V2 Mode : Disabled VTP Traps Generation : Disabled MD5 digest : 0x28 0xDE 0x37 0xB2 0xF6 0xE9 0x36 0x7A Configuration last modified by 10.200.200.1 at 11-7-06 04:43:32 Local updater ID is 10.200.200.1 on interface Vl1 (lowest numbered VLAN interface found)

Port Fa0/19 has switchport access vlan 100 set on it but I am not seeing VLAN100 in the list

If anyone could offer any ideas it would bemost appreciated

Okay, so first part, is your VTP isn't working. Not sure if you are thinking it should..

So, they aren't seeing any pushdowns of VTP data, so they won't learn of VLANs automatically. The displays show that they should be doing VTP, but something isn't working there, since the config rev's are 0 on the clients and not matching the config rev on the VTP server.

With the switch in VTP client mode, it won't automake the VLAN into the list when applied on a switch port.

Either figure out what in VTP isn't working, or manually create all VLANs on each switch and ignore VTP altogether with the 'vlan xx' config item.
