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