Networking requirements
As shown in Figure 2-21, GE 1/1/2 and GE 1/1/3 on Switch A are connected to the user
network. To avoid loops on the user network, enable loop detection on Switch A to detect
loops on user network, and then take actions accordingly. Detailed requirements are as below:
Enable loop detection on GE 1/1/2 and GE 1/1/3.
Configure the interval for sending loop detection packets to 3s.
Configure the VLAN for sending loop detection packets to VLAN 3.
Configure the loop detection processing action to discarding, namely, sending Trap and
blocking the interface.
