Multiple spanning tree protocol (MSTP), as implemented by the Dell Networking operating system, conforms to IEEE 802.1s.

This command supports the Dell Networking S6000 platform.

debug spanning-tree mstp

Enable debugging of the multiple spanning tree protocol and view information on the protocol.

S6000

Syntaxdebug spanning-tree mstp [all bpdu interface {in out} events]

To disable debugging, enter no debug spanning-tree mstp

Parameters

all

bpdu

interface {in out}

events

(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 port- channel 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.

(OPTIONAL) Enter the keyword events to debug MSTP events.
