    Added a couple vlans on the 6500 that weren't updated on the 3750. I
    tried toggling the 3750 client (stack of 4) to transparent and back to
    client - no change in cfg. thanks

    Whether these 2 devices are connected directly or how are these devices
    connected ?? Please make sure that the links are in trunk mode for the
    vlans to be propogated.

    ok It should work then, I donno why is it not getting updated which is
    evident from the output of Config revision number and no. of
    vlans....Have you configured any passwords for the vtp domain...if so,
    make sure that all the switches configured with the same password.

  5. How many switches are in your network?

    Are the other switches all receiving the correct number of VLANS?


    On the 3750 you many have a space after you domain name ussfof. May check
    that.

    On the show vtp stat your Number of existing VLANs should be the same 24 if
    client and server.

    try "deb sw-vlan vtp". otherwise it's just blind guessing

    http://www.cisco.com/en/US/products...erence_chapter09186a0080102724.html#wp1022361


    eventually may help.
    my predecessors already gave you a few hints. password for the
    vtp-domain, not allowing vlan 1.
    sounds stupid, but try adding a vlan, applying the change, and removing
    the vlan again. worked for me.

    greetings

    Thanks for this suggestion. I removed a vlan from the server switch and
    saw the vtp packet hit the client switch with the latest vlan info, but
    still the vtp config rev didn't increment and the vlan info remained
    unchanged on the client. I'm mystified. If all else fails I plan to
    reboot the master switch after hours.
