[c-nsp] Vlans and catalyst 2950

[Alban Dani]

Hello Matthew,

I also am having a very wierd issue with vlans and 2950-s.

We are running pst+.
We have a 6509 in the core and everytime we try to get a new vlan
passed through a chain  of switches( all connected via dot1q trunks) 
that has a 2950 in it, it does not work. The only workaround we found
so far is to go to a port on the given 2950 , set the port on the
requried vlan and connect a machine to it and through some traffic.
That makes the 2950 aware of  that vlan.

If this was not enough, if the vlan in question does not see traffic
for a couple of days the 2950 totally forgets about it.

I am wondering if you ever found a solution to your problem and if so
what was it?

I have upgraded to the latest IOS but it did not help.

thanks,

Alban
