all: Enables output of port state transition information for all MSTIs.  

instance instance-id: Enables output of port state transition information for the specified MSTI. The 

value of instance-id ranges from 0 to 31. The minimum value is 0, representing the CIST.  

Use the stp port-log command to enable output of port state transition information for the specified 

MSTI or all MSTIs.  

Use the undo stp  port-log command to disable output of port state transition information for the 

specified MSTI or all MSTIs.  

By default, this function is enabled.

instance instance-id: Sets the priority of the device in a particular spanning tree instance. The value of 

instance-id ranges from 0 to 31. The minimum value is 0, representing the CIST.  

priority: Port priority, in the range of 0 to 61440 in steps of 4096, namely you can set up to 16 priority 

values, such as 0, 4096, 8192…, on the device.  

Use the stp priority command to set the priority of the device.  

Use the undo stp priority command to restore the default device priority.  

By default, the device priority is 32768.
