Chapter 7 Loop Detection

The following figure shows a loop detection enabled port N on switch A sending a
probe frame P to switch B . Since switch B is in loop state, the probe frame P
returns to port N on A . The Switch then shuts down port N to ensure that the rest
of the network is not affected by the switch in loop state.

Note: After resolving the loop problem on your network you can re-activate the
disabled port via the web configurator or via commands (See the CLI Reference
Guide).
