Hello everyone
I have been unable to place a few switches in spanning-tree debug mode using the debug spanning-tree events. The command gets returned as invalid input in priviliged EXEC mode. In other modes it is retured as an unrecognized command. I looked into the configuration of the spanning tree in the show spanning-tree output and it seems all fine. Please advise me how to enable this debugging functionality.
Thank you for reading,

Use the debug spanning-tree privileged EXEC command to debug spanning-tree activities. Use the no form of this command to disable debugging output.
debug spanning-tree {all | backbonefast | bpdu | bpdu-opt | config | csuf | etherchannel | events | exceptions | general | mstp | pvst+ | root | snmp | switch | uplinkfast}
no debug spanning-tree {all | backbonefast | bpdu | bpdu-opt | config | csuf | etherchannel | events | exceptions | general | mstp | pvst+ | root | snmp | switch | uplinkfast}
