Here is the problem we are having , we have a 2950 hooked to a 6509 hybrid dist box with approx 90 vlans on it . We hook up a new 2950 and we get the following message, Dec 21 19:47:45.116: %SPANTREE_VLAN_SW-2-MAX_INSTANCE: Platform limit of 64 STP instances exceeded. No instance created. Ok , I know about the spanning tree issues with the 2950 only having limited PVST instances . But up at the dist side we have "manually pruned off all but 5 vlans on the trunk feeding this 2950 with the "clear trunk" command . I thought manually pruning off the vlans from the trunk would eliminate this problem , maybe i have a misunderstanding of how this works. Also the message on the 2950 complains about it only having 64 instances of spanning tree yet when you do a "show vtp status it says it supports 250 instances locally so whats up with that , 2950 running 12.1.22EA4 . So I guess I'm asking is there any way around this for the 2950 . Also in client/server mode do you have to manually prune off the vlans on both the server side and the client side ??
