Syntax
debug spanning-tree mstp [all | bpdu interface {in | out} | events]
Parameters
all (OPTIONAL) Enter the keyword all to debug all spanning tree operations.
bpdu interface
{in | out}
(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.
events (OPTIONAL) Enter the keyword events to debug MSTP events.
