I have a hub and spoke network with 7750 at the center and about 20 or so 7250/7150 switches(some in 2-3 switch stacks). There is a network outside of my control but utilizing my 7250/7150 switches for interconnect. i have 802.1w enabled for this vlan as well as loop-detection(under the vlan). What iv noticed is when that network gets a mac loop, instead of my edge port disabling, the uplink to the core goes down. Sometimes switches across the network will also go down. Its currently causing chaos in my network when this happens.
I have spanning-tree 802-1w admin-edge-port enabled on all edge ports and spanning-tree 802-1w admin-pt2pt-mac enabled on all uplinks. I have had support go over my config twice now and have told me the configuration is correct, but they havent been able to explain this behavior to me.
What am i missing?
