debug spanning-tree
debug spanning-tree
Use the debug spanning-tree privileged EXEC command to enable debugging of spanning-tree
activities. Use the no form of this command to disable debugging.
debug spanning-tree {all | backbonefast | bpdu | bpdu-opt | config | etherchannel | events |
exceptions | general | mstp | pvst+ | root | snmp | switch | synchronization | uplinkfast}
no debug spanning-tree {all | backbonefast | bpdu | bpdu-opt | config | etherchannel | events |
exceptions | general | mstp | pvst+ | root | snmp | switch | synchronization | uplinkfast}
Syntax Description
Note Though visible in the command-line help strings, the csuf/csrt keyword is not supported.
Defaults Debugging is disabled.
Command Modes Privileged EXEC
Command History
all Display all spanning-tree debug messages.
backbonefast Display BackboneFast-event debug messages.
bpdu Display spanning-tree bridge protocol data unit (BPDU) debug messages.
bpdu-opt Display optimized BPDU handling debug messages.
config Display spanning-tree configuration change debug messages.
etherchannel Display EtherChannel-support debug messages.
events Display spanning-tree topology event debug messages.
