What is the mandatory BPDU configuration on the switches where the VEM is connected?
on the upstream switches that the VEM is connected to it is highly recommneded to that Global BPDU Filtering and BPDU Guard be enabled. For IOS cat65k-1(config)# spanning-tree portfast bpdufilter cat65k-1(config)# spanning-tree portfast bpduguard For NXOS n5k-1(config)# spanning-tree port type edge bpduguard default n5k-1(config)# spanning-tree port type edge bpdufilter default In environments where you can NOT use global modes set the following on the switchports the VEM are connected to For IOS cat65k-1(config-if)#spanning-tree bpdufilter cat65k-1(config-if)#spannning-tree bpduguard For NXOS n5k-1(config-if)#spanning-tree bpdufilter n5k-1(config-if)#spanning-tree bpduguard Q: When I try to connect the VSM to vCenter I get “Extension Key was not registered before it’s use” This error means the key stored on the VSM is not matching the key that has been loaded into vCenter Server.
