Multiple spanning tree protocol (MSTP), as implemented by the Dell Networking OS, conforms to IEEE
802.1s.
This command supports the Dell Networking platform.
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. The range is from 1 to 128.
• For a 1-Gigabit Ethernet 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.
