Cisco Router: Ethernet excessive collisions Health Monitor

Jalasoft.Xian.SmartManagementPacks.CiscoRouters.EthernetExcessiveCollisions.1.1 (AggregateMonitor)

This monitor catches Xian events that notifies when the Ethernet excessive collisions if has changed its state.

Knowledge Base article:

Summary

Number of ethernet excessive collisions is over threshold.

The number of frames that fail due to excessive collisions is above the maximum threshold configured in Xian Network Manager 2012.

Causes

An increment of this counter is an indication of a wiring problem, an excessively loaded network, or a duplex mismatch. An excessively loaded network could be due to having too many devices on a shared ethernet.

Resolutions

Verify the wiring, the loaded network, or the presence of a duplex mismatch.

Additional

Monitors the number of frames for which transmission on a particular interface fails due to excessive collisions.
