ProSafe M4100 and M7100 Managed Switches no debug spanning-tree bpdu receive This command disables tracing of received spanning tree BPDUs. Format Mode no debug spanning-tree bpdu receive Privileged EXEC debug spanning-tree bpdu transmit This command enables tracing of spanning tree BPDUs transmitted by the switch. Spanning tree should be enabled on the device and on the interface in order to monitor packets on a particular interface. Default Format Mode disabled debug spanning-tree bpdu transmit Privileged EXEC A sample output of the trace message is shown below.
