OutDiscards count continues to increase.
Is there a possibility of an issue occurring on the network?

[Joseph W. Doherty]

A 2960X does have limited buffer resources compared to its larger Enterprise siblings.

[JustTakeTheFirstStep]

Is there a way to increase the buffer of 2960?
How do I check the buffer of the system?

[Joseph W. Doherty]

Increase buffers - yes and no. There's only so much physical RAM available to support buffers, so it cannot actually (generally) be increased. However, often it can be configured to make more available where/when needed (by reducing allocations for where/when not needed).

How to check depends on the switch and the IOS, but I recall the 2960 series is much like the 3750 series which support a set of show ASIC commands that provide additional stats.
