What is xylanHrexPseudoCamHashFree?

This read-only Counter reports the number of HRE-X PseudoCAM hash entries that are currently not in use, out of the total configured. An admin monitors this to catch when the PseudoCAM hash table is nearing exhaustion, which could affect the HRE-X's ability to add new forwarding entries. For example, a free-entry count trending toward zero signals it may be time to trigger a hash optimization via xylanHrexHashOptimize.

Examples
