VTP probs after insert new 2960G with CNA4.1

    All our switches (3550, 2950 etc.) were running since months perfectly.
    First we applied a 2960G in the network and configured it with the CNA 4.1.
    All vlans were synchronized to the new device and everything worked well. I
    configured some ports with the CNA as trunk and "Trunk-allowed VLAN" with
    one of the VLAN as example "4". Now to my problem ;-) After we inserted a
    second new 2960 switch, I can't set any of the 2960 family switches a port
    to trunk with only one vlan as "Trunk-allowed VLAN". If I set a port to
    trunk with Vlan 4 I can apply that setting but after a refresh the
    "Trunk-allowed VLAN" is set to "ALL" every time! The problem occurs only
    with all new 2960 series switches. All old (3550 or 2950) I can set
    "Trunk-allowed VLAN" only to 4 and that works fine. Could it be, that VTP
    has corrupted my settings on the new 2960 series switches? All
    vtp-parameters looked well on these switches and VLANS are also all defined
    and active.

    Any suggestions?
    Thx Wayne

    P.S. Sorry for my bad english ;-)

    It looks like that's a bug in the CNA because in the CLI I can set only
    some VLAN's but not ALL.
