HP ProCurve Switch: Failed reassembly requests Health Monitor

Jalasoft.Xian.SmartManagementPacks.HPProCurveSwitches.FailedReassemblyRequests.1.1 (AggregateMonitor)

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

Knowledge Base article:

Summary

Number of failed reassembly requests is over threshold.

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

Causes

If the count is at a suspect level, there might be a capacity problem; however, this is not necessarily a count of discarded IP fragments.

Resolutions

Verify that the threshold is set at a reasonable value. It is also possible to design an internal network to avoid fragmentation and the subsequent reassembly requirement.

Additional

Monitors the number of reassembly requests that have failed.
