xylanHrexCollisionLengthMax
Module: XYLAN-HREX-MIB
OID (symbolic): XYLAN-HREX-MIB::xylanHrexCollisionLengthMax
OID (numeric): 1.3.6.1.4.1.800.2.31.3.7
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The longest collision chain currently in use in the HRE-X.
What is xylanHrexCollisionLengthMax?
This read-only Counter reports the longest hash-collision chain currently in use in the HRE-X PseudoCAM. An admin watches this value as an indicator of hash-function efficiency, since longer chains mean slower worst-case lookups. For example, a growing maximum chain length over time would be a reason to trigger xylanHrexHashOptimize to recompute a better-distributed hash.
