debug spanning-tree mstp
Enable debugging of the multiple spanning tree protocol and view information on the protocol.
Syntax
debug spanning-tree mstp [all | bpdu interface {in | out} | events]
To disable debugging, enter no debug spanning-tree mstp
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.
• For a 1-GigabitEthernet interface, enter the keyword GigabitEthernet then the
slot/port information.
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet 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.
