This monitor catches Xian events that notifies when the Free large buffers has changed its state.
Number of free large buffers is under threshold.
The number of available large buffers is below the minimum threshold configured in Xian Network Manager 2012.
The switch is assigning packets to an excessive amount of large buffers in order to manage them according to requirements, but they are not releasing them, thus generating insufficiency of free large buffers. It can be done because of a buffer leak.
Analyze the buffer sizes and strategies for handling overflows and reconfigure. Sometimes it can be solved just by updating your Cisco IOS. Use 'show buffers old' command to get more information and find the problem.
Monitors the number of free large buffers on a Cisco Switch.
