Step 2: Enable topology protection on the interface.
! Enable topology protection on the AP ports connecting core devices.
DES-7200(config)#interface aggregateport 1
DES-7200(config-if-AggregatePort 1)#tp-guard port enable
! Enable topology protection on the ports connecting downlink devices.
DES-7200(config)#interface range gigabitEthernet 0/3-6
DES-7200(config-if-range)#tp-guard port enable
Step 3: Configure the threshold for detecting CPU utilization.
! When CPU utilization exceeds 60%, the system will generate topology
protection advertisement.
DES-7200(config)#cpu topology-limit 60
¾ Configurations on Switch C/D/E/F
Step 1: Global topology protection is enabled by default. If it is disabled, use
the following command to enable topology protection.
DES-7200# config terminal
DES-7200(config)# topology guard
Step 2: Enable topology protection on the interface.
DES-7200(config)#interface range gigabitEthernet 0/1-2
DES-7200(config-if-range)#tp-guard port enable
Step 3: Configure the threshold for detecting CPU utilization.
! When CPU utilization exceeds 60%, the system will generate topology
protection advertisement.
DES-7200(config)#cpu topology-limit 60
