Cisco Router: DS1 total severely errored framing seconds Health Monitor

Jalasoft.Xian.SmartManagementPacks.CiscoRouters.DS1TotalSeverilyErroredFramingSeconds.1.1 (AggregateMonitor)

This monitor catches Xian events that notifies when the DS1 total severely errored framing seconds has changed its state.

Knowledge Base article:

Summary

Number of DS1 Total Severely Errored Framing Seconds is over threshold.

The number of Current Severely Errored Seconds in the previous 24-hour interval is above the maximum threshold configured in Xian Network Manager 2012.

Causes

A Severely Errored Framing Second is a second with one or more Out of Frame defects OR a detected AIS defect.

Excessive Path Code Violation Error Events, Out of Frame defects, or a detected AIS defect.

Resolutions

Verify the framing format configured on the port matches the framing format of the line in the show controller e1 output. Once an Out of Frame defect is declared, the framer starts searching for a correct framing pattern and ends when the signal is in frame. The Alarm Indication Signal failure is declared when an AIS defect is detected at the input and the AIS defect still exists after the Loss Of Frame failure which is caused by the unframed nature of the 'all-ones' signal is declared. The AIS failure is cleared when the Loss Of Frame failure is cleared.

Additional

This rule monitors the number of Severely Errored Framing Seconds encountered by a DS1 interface in the previous 24-hour interval.
