CLI Reference  TPP Configuration Commands 
Interface configuration mode. 
If  both  the  global  topology  protection  function  and  the  topology 
protection function of the port are enabled, the remote device of this 
port will be notified when the CPU utilization of the local device is too 
high or there are other problems with the local device. This command 
is applicable to the layer 2 switching interfaces and routing interfaces. 
Other  interfaces  (including  AP  member  port)  do  not  support  this 
command. 
The  following  example  shows  how  to  configure  the  topology 
protection function for the port: 
Ruijie(config-if)# tp-guard port enable 
Ruijie(config-if)# no tp-guard port enable 
Enable the topology protection function globally. 
 
show tpp 
Use this command to show the configuration of topology protection. 
show tpp 
This command is used to view the current TPP configuration and port 
detection. 
The following example shows how to display information about the 
topology protection function: 
Ruijie# show tpp
