4Spanning Tree Protocol and derivativesdebug spanning-tree showSyntax: [no] debug spanning-tree showThis command generates information about the STP debug configuration. The following commandoutput shows the default configuration.Brocade# debug spanning-tree showSTP Debug Parameters--------------------STP debugging is ON [Mode: Brief]NonBpduEvents ConfigBpduEvents TcnBpdusEvents are being trackedPorts: AllVLANs: Alldebug spanning-tree tcn-bpduSyntax: [no] debug spanning-tree tcn-bpduThis command displays information about TCN BPDU events. Command output resembles thefollowing example.Brocade# debug spanning-tree tcn-bpduSTP: Sending TCN BPDU - VLAN 10 Port 3/20STP: TCN ACK Received - VLAN 10 Port 3/20debug spanning-tree verboseSyntax: [no] debug spanning-tree verboseIn verbose mode, STP BPDU information is translated into BPDU fields and values, which are easierto read than the default hex output. Command output resembles the following example.Brocade# debug spanning-tree verboseSTP: Sending Config BPDU - VLAN 2 Port 2/2protocol-id: 0000protocol-version: 00type: 00flags: 00root-id: 800000000001c040path-cost: 00000000bridge-id: 800000000001c040port-id: 8042message-age: 0000max-age: 0000hello-time: 0000hello-time: 0000debug spanning-tree vlanSyntax: [no] debug spanning-tree vlan This command restricts debug output to a specific VLAN.

Spanning Tree Protocol and derivatives 4MSTP debug commandsThis section describes the MSTP-related debug commands.debug mstpSyntax: [no] debug mstp [bpdu | event | mstid | port [ethernet | pos] | show | state | verbose]• bpdu - Displays MSTP BPDU and MRecord events.• event - Displays MSTP state machine events.• mstid - Displays debug information for a specific MSTP instance.• port - Displays debug information about a specific MSTP port.• show - Displays current MSTP debug parameters.• state - Displays debug information about MSTP port state events.• verbose - Displays MSTP debug information in the verbose mode.This command generates information about MSTP BPDUs and events. Command output resemblesthe following example.Brocade# debug mstp bpduMSTP Bpdu debugging ONBrocade# debug mstp stateMSTP Port State debugging ONBrocade# debug mstp mstid ?DECIMAL MSTid (1-4094 : MSTI, 0 : CIST)Brocade# debug mstp mstid 0MSTP debugging turned on for instances (indices) 16Brocade# debug mstp port e 3/1MSTP debugging turned on for ports ethe 3/1Brocade# debug mstp verboseMSTP debugging set to VERBOSE modeBrocade# show debugDebug message destination: ConsoleBrocade# debug mstpMSTP: debugging is onR1#Dec 10 19:57:31 MSTP: PRS ROLE_SELECTION->ROLE_SELECTION - MST 0Dec 10 19:57:31 MSTP: PRX RECEIVE->RECEIVE - Port 3/1Dec 10 19:57:31 MST 0, Port 3/1 - received BPDUprotocol-id: 0000protocol-version: 00type: 00flags:root-id: 80000024387c9301path-cost: 00000000bridge-id: 80000024387c9301port-id: 8031message-age: 0000max-age: 0014hello-time: 0002forward-delay: 000fDec 10 19:57:31 MSTP: PIM CURRENT->RECEIVE - MST 0, Port 3/1Dec 10 19:57:31 MSTP: PIM RECEIVE->OTHER - MST 0, Port 3/1Dec 10 19:57:32 MSTP: PTX IDLE->TRANSMIT_PERIODIC - Port 3/1Dec 10 19:57:32 MSTP: PTX IDLE->TRANSMIT_CONFIG - Port 3/1Dec 10 19:57:32 MST 0, Port 3/1 - sent Config BPDUprotocol-id: 0000Brocade MLX Series and Brocade NetIron XMR Diagnostic Guide 9153-1002426-02
