Fault Detection

The automatic fault detection feature protects your network from failing because of problems such as network loops, defective cables, transceivers and faulty network interface cards. Network problems are automatically detected and entered in the Alert Log. The Fault Detection page lets you set the sensitivity levels for the actions to be taken when a fault is detected on a port in your network. Switches only have a sensitivity setting for logging network problems. The sensitivity settings are:

High Sensitivity: The device will make an entry in the Alert Log (located in the Status tab) when a network problem of any severity occurs.

Medium Sensitivity: The device will make an entry in the Alert Log when serious network problems occur.

Low Sensitivity: The device will make an entry in the Alert Log only when severe network problems occur. These are problems that may bring the network down.

Never: The device will never make any entries in the Alert Log regardless of the severity of the problem.
