Hi all

Please correct me if i'm wrong but i think this is related to a platform limitation. You will run into different (64 up to 256) spanning tree instances depending on the platform, specifically fixed switches. I am not sure about the modular catalyst. We had the same issue in the past, we solved the problem by upgrading from a 2960 to a 3750 catalyst.

Hello all,

We have run into an issue on a 3750 switch where it has run out of spanning tree instances.

Is this a limitation of PVST or is it a limitation of the switch? I can't seem to find good clarity anywhere. I have some 6509's and nexus 7k's and I'm wondering if they're going to suffer from the same fate...
