Jalasoft.Xian.SmartManagementPacks.CiscoSwitches.BigBufferCreated.1.1 (AggregateMonitor)

This monitor catches Xian events that notifies when the Big buffer created if has changed its state.

Knowledge Base article:

Summary

Number of created big buffers is over threshold.

The number of created big buffers is above the maximum threshold configured in Xian Network Manager 2012.

Causes

After buffer failures, the switch is creating an excessive amount of big buffers in order to manage packets according to requirements due to insufficient free big buffers.

Resolutions

Analyze buffer sizes and strategies for handling overflows and perform buffer tuning by increasing minimal number of free big buffers.

Additional
