SWITCH
Network Topology
Figure 9-1: Typical example of port loopback dete
ction
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
Switch(config)#interface ethernet 1/1
