34 Multiple Spanning Tree Protocol (MSTP) Multiple spanning tree protocol (MSTP), as implemented by the Dell Networking operating system, conforms to IEEE 802.1s. debug spanning-tree mstp Enable debugging of the multiple spanning tree protocol and view information on the protocol. C9000 Series Syntax Parameters debug spanning-tree mstp [all | bpdu interface {in | out} | events] all bpdu interface {in | out} (OPTIONAL) Enter the keyword all to debug all spanning tree operations. (OPTIONAL) Enter the keyword bpdu to debug bridge protocol data units (BPDU). (OPTIONAL) Enter the interface keyword along with the type slot/port of the interface you want displayed. Type slot/port options are the following: • For a Port Channel interface, enter the keywords portchannel then a number. The range is from 1 to 128. • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port information. • For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information. Optionally, enter an in or out parameter with the optional interface: • For Receive, enter the keyword in. • For Transmit, enter the keyword out. events (OPTIONAL) Enter the keyword events to debug MSTP events.
