Chapter 8 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 MES-2110 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).
