6.3 Port Loopback Detection

Function Example

Typical example of port loopback detection

As shown in the above configuration, the switch will detect the existence of loopbacks in the

network topology. After enabling the function of loopback detection on the port connecting the

switch with the outside network, the switch will notify the connected network about the

existence of a loopback, and control the port on the switch to guarantee the normal operation

of the whole network.

The configuration task sequence of SWITCH:

Switch(config)#loopback-detection interval-time 35 15
