5.4. Network Configuration Example and Notes
Using Loop Detection and Blocking Function
Configuration example using the Loop detection and blocking function
Using the Loop detection and blocking function allows to prevent a loop failure
possibly occurring on a downstream switch that the user directly uses.
If you connect a hub that does not support the Loop detection and blocking func
-
tion to a downstream switch, and a loop failure occurs in the switch, the down
-
stream switch port that caused a loop is blocked to prevent a loop failure from
affecting the entire network.
