9 debug spanning-tree DRAFT: BROCADE CONFIDENTIAL debug spanning-tree Synopsis Operands Defaults Command Modes Description Usage Guidelines Examples See Also Enables debugging for the Spanning Tree Protocol. debug spanning-tree {all | bpdu {rx | tx {all | interface port-channel number | tengigabitethernet slot/port} } no debug spanning-tree {all | bpdu {rx | tx {all | interface port-channel number | tengigabitethernet slot/port} } all Turns on spanning tree packet debugging on all interfaces. bpdu Turns on Bridge Protocol Data Unit debugging. rx Turns on debugging for only received spanning-tree packets. tx Turns on debugging for only transmitted spanning-tree packets. interface port-channel number Specifies the port-channel interface. The range of valid values is 1-63. interface tengigabitethernet Specifies the 10 Gbps Ethernet interface. slot Specifies the slot number. port Specifies the port number. By default debugging is not turned on. Privileged EXEC mode Use this command to enable debugging for the Spanning Tree Protocol. Use the no debug command to disable debugging. To display debugging outputs on a particular cmsh session, use the terminal monitor command. To enable debugging of spanning-tree for both Rx and Tx on 10 Gbps Ethernet interface 0/1: switch#debug spanning-tree bpdu rx interface tengigabitethernet 0/1 switch#debug spanning-tree bpdu tx interface tengigabitethernet 0/1 switch#show debug spanning-tree MSTP debugging status: Spanning-tree rx debugging is off Te 0/1 rx is on Spanning-tree tx debugging is off Te 0/1 tx is on show debug spanning-tree, show debug 128 Converged Enhanced Ethernet Command Reference 53-1001762-01
