cpqn52nnHashChainNum
Module: CPQN5226A-MIB
OID (symbolic): CPQN5226A-MIB::cpqn52nnHashChainNum
OID (numeric): 1.3.6.1.4.1.232.101.2.2.7.1.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: A count of indices in the Address Filter/Forward mechanism's hash table which have more than one MAC Address entry.
What is cpqn52nnHashChainNum?
This read-only counter reports how many indices in the interface's Address Filter/Forward hash table have more than one MAC address entry mapped to them (hash collisions). An admin monitors this as an indicator of hash table efficiency; a high number of chained indices can slow down address lookups. For example, an increasing chain count as the MAC table fills up suggests the interface is approaching capacity limits for efficient address lookups.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.232.101.2.2.7.1.3 snmpwalk -v2c -c public <target> CPQN5226A-MIB::cpqn52nnHashChainNum
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.232.101.2.2.7.1.3.1 snmpget -v2c -c public <target> CPQN5226A-MIB::cpqn52nnHashChainNum.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> cpqn52nnHashChainNum.1
