Page 987: Debug Pm
Appendix B Cisco Catalyst Blade Switch 3130 and 3032 for Dell Debug Commands debug pm debug pm Use the debug pm privileged EXEC command to enable debugging of port manager (PM) activity. The port manager is a state machine that controls all the logical and physical interfaces. All features, such as VLANs, UniDirectional Link Detection (UDLD), and so forth, work with the port manager to provide switch functions.

Page 991: Debug Spanning-Tree
Appendix B Cisco Catalyst Blade Switch 3130 and 3032 for Dell Debug Commands 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.
Page 992 Appendix B Cisco Catalyst Blade Switch 3130 and 3032 for Dell Debug Commands debug spanning-tree Command History Release Modification 12.2(40)EX1 This command was introduced. Usage Guidelines The undebug spanning-tree command is the same as the no debug spanning-tree command. On a stacking-capable switch, when you enable debugging, it is enabled only on the stack master. To enable debugging on a stack member, you can start a session from the stack master by using the session switch-number privileged EXEC command.

Appendix B Cisco Catalyst Blade Switch 3130 and 3032 for Dell Debug Commands debug spanning-tree backbonefast debug spanning-tree backbonefast Use the debug spanning-tree backbonefast privileged EXEC command to enable debugging of spanning-tree BackboneFast events. Use the no form of this command to disable debugging.
Page 994: Debug Spanning-Tree Bpdu
Appendix B Cisco Catalyst Blade Switch 3130 and 3032 for Dell Debug Commands debug spanning-tree bpdu debug spanning-tree bpdu Use the debug spanning-tree bpdu privileged EXEC command to enable debugging of sent and received spanning-tree bridge protocol data units (BPDUs). Use the no form of this command to disable debugging.
Page 995: Debug Spanning-Tree Bpdu-Opt
Appendix B Cisco Catalyst Blade Switch 3130 and 3032 for Dell Debug Commands debug spanning-tree bpdu-opt debug spanning-tree bpdu-opt Use the debug spanning-tree bpdu-opt privileged EXEC command to enable debugging of optimized spanning-tree bridge protocol data units (BPDUs) handling. Use the no form of this command to disable debugging.
Page 996: Debug Spanning-Tree Mstp
Appendix B Cisco Catalyst Blade Switch 3130 and 3032 for Dell Debug Commands debug spanning-tree mstp debug spanning-tree mstp Use the debug spanning-tree mstp privileged EXEC command to enable debugging of the Multiple Spanning Tree Protocol (MSTP) software. Use the no form of this command to disable debugging.
Page 997 Appendix B Cisco Catalyst Blade Switch 3130 and 3032 for Dell Debug Commands debug spanning-tree mstp Usage Guidelines The undebug spanning-tree mstp command is the same as the no debug spanning-tree mstp command. On a stacking-capable switch, when you enable debugging, it is enabled only on the stack master. To enable debugging on a stack member, you can start a session from the stack master by using the session switch-number privileged EXEC command.
Page 998: Debug Spanning-Tree Switch
Appendix B Cisco Catalyst Blade Switch 3130 and 3032 for Dell Debug Commands debug spanning-tree switch debug spanning-tree switch Use the debug spanning-tree switch privileged EXEC command to enable debugging of the software interface between the Spanning Tree Protocol (STP) software module and the port manager software module.
Page 999 Appendix B Cisco Catalyst Blade Switch 3130 and 3032 for Dell Debug Commands debug spanning-tree switch Usage Guidelines The undebug spanning-tree switch command is the same as the no debug spanning-tree switch command. On a stacking-capable switch, when you enable debugging, it is enabled only on the stack master. To enable debugging on a stack member, you can start a session from the stack master by using the session switch-number privileged EXEC command.
