So I have a mixed environment of switches:
-3 x 3 stacks of Dell N1548 rapid-pvst, rstp, mst
-2xDell 4048 rstp, pvst, mst
-15 Cisco C2960L-16ts-LL rapid-pvst, pvst+, mst
The issue i'm having is if there is a change to one of Cisco's config all the Cisco switches will blip and drop for 1-2 minutes. For example setting a port on the Cisco to trunk to the main network, change default vlan etc. I'm not really sure what is causing this. My only hunch is it has something to do with spanning-tree, but I could be really far off base.
Anyone ever see this type of behavior before? Any suggestions would be greatly appreciated.
