Chapter 7 Loop Detection

MES-2110 User’s Guide

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).
