Cisco Wireless: Reassembly requests Health Monitor

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

This monitor catches Xian events that notifies when the Reassembly requests if has changed its state.

Knowledge Base article:

Summary

Reassembly requests are over threshold.

The number of reassembly requests is above the maximum threshold configured in Xian Network Manager 2012.

Causes

If the counter is at a suspect level, it may be a capacity problem, but this procedure may be necessary because every network that a packet has traveled over, could have a different frame size.

Resolutions

Verify network configuration in order to establish if the high amount of reassembly requests is correct.

Additional

Monitors the number of reassembly requests that were received on the Cisco Wireless device.
