Hi

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.
