Cisco Wireless: Packets received Health Monitor

Jalasoft.Xian.SmartManagementPacks.CiscoWireless.PacketsReceived.1.1 (AggregateMonitor)

This monitor catches Xian events that notifies when the Packets received has changed its state.

Knowledge Base article:

Summary

Number of received packets is over threshold.

The number of packets received is above the maximum threshold configured in Xian Network Manager 2012.

Causes

Excess of incoming network traffic through a Cisco Wireless device. Also, when two antennas are aligned to the edges of their radiation patterns, communication can be marginal as indicated by lost packets, high retry counts, and a low signal strength.

Resolutions

Monitor the origin of incoming traffic and reestablish control parameters, if necessary. Upgrading might be required in order to respond in case of growing demand. When two antennas are properly aligned, communication is improved as indicated by all packets being received.

Additional

Monitors the packets received from a Cisco Wireless interface.
