Is anyone aware of a logical port limit on the 2950T-24s, as there is
with the 6500s? I've had a google and looked on CCO and I can't find
anything but it appears if there is a limit that it's 127 or 128.

We have a trunk link between a 7600 and a 2950 that's suddenly started
flapping every time there's a change elsewhere in the network and can
only be fixed by removing and readding all the VLANs to that trunk
link - the switch currently has 126 logical ports, excluding VLAN1.
(The port comes up normally, but goes down as soon as spanning-tree
goes from listening to forwarding state, then comes back up again a
second later... only to repeat when spanning tree eventually goes into
forwarding state again)
