xylanHrexPseudoCamCollisionFree

Module: XYLAN-HREX-MIB

OID (symbolic): XYLAN-HREX-MIB::xylanHrexPseudoCamCollisionFree

OID (numeric): 1.3.6.1.4.1.800.2.31.3.4

Node type: OBJECT-TYPE

Type: Counter

Access: read-only

Description: The total number of HRE-X PseudoCAM collision entries that are currently not in use.

What is xylanHrexPseudoCamCollisionFree?

This read-only Counter reports the number of HRE-X PseudoCAM collision entries that are currently not in use, out of the total configured. An admin watches this to see if collision-entry capacity is running low, which alongside long collision chains could hint the hash function needs re-optimization. For example, a free-collision-entry count nearing zero combined with a high xylanHrexCollisionLengthMax would prompt the admin to run xylanHrexHashOptimize.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.800.2.31.3.4
snmpwalk -v2c -c public <target> XYLAN-HREX-MIB::xylanHrexPseudoCamCollisionFree

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.800.2.31.3.4.1
snmpget -v2c -c public <target> XYLAN-HREX-MIB::xylanHrexPseudoCamCollisionFree.1
