Clearing spanning-tree-detected protocols
In Privileged EXEC mode, restart the protocol migration process (force the renegotiation with
neighboring switches) on all interfaces or on the specified interface.
To restart the protocol migration process, perform the following tasks from Privileged EXEC mode:
Displaying STP, RSTP, and MSTP-related information
To display STP, RSTP, and MSTP-related information, perform the following tasks from Privileged
EXEC mode:
Step Task Command
1. Clear all spanning-tree-detected protocols on
all interfaces.
switch#clear spanning-tree
detected-protocols
Clear the spanning-tree-detected protocol
associated with a specific port-channel or CEE
port interface. The range of port-channel
numbers is 1 through 63.
switch#clear spanning-tree
detected-protocols [interface
{port-channel number |
tengigabitethernet slot/port}]
2. Display the spanning-tree configuration. switch(conf-stp)#do show spanning-tree
Task Command
Display all STP, RSTP, and MSTP-related
information.
switch#show spanning-tree [brief | interface {port-channel number |
tengigabitethernet slot/port}]
Display MSTP-specific information. switch#show spanning-tree mst [brief | detail [interface {port-channel
number | tengigabitethernet slot/port}] | instance {instance_id}
[interface {loopback number | port-channel number |
tengigabitethernet slot/port | vlan number}] | interface {port-channel
number | tengigabitethernet slot/port}]
