cadAgingArpCacheAgingInterval
Module: CADANT-CMTS-LAYER2CMTS-MIB
OID (symbolic): CADANT-CMTS-LAYER2CMTS-MIB::cadAgingArpCacheAgingInterval
OID (numeric): 1.3.6.1.4.1.4998.1.1.20.1.2.4
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: Arp cache Aging time in seconds.
What is cadAgingArpCacheAgingInterval?
This object controls how long ARP (Address Resolution Protocol) cache entries are retained before expiration, measured in seconds (10 minutes to 100 hours, defaulting to 20 minutes). Cable modem termination system (CMTS) operators adjust this to balance memory usage against stale ARP entries in their networks. Longer aging intervals preserve learned MAC-to-IP mappings but consume more cache memory.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4998.1.1.20.1.2.4 snmpwalk -v2c -c public <target> CADANT-CMTS-LAYER2CMTS-MIB::cadAgingArpCacheAgingInterval
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.4998.1.1.20.1.2.4.1 snmpget -v2c -c public <target> CADANT-CMTS-LAYER2CMTS-MIB::cadAgingArpCacheAgingInterval.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.4998.1.1.20.1.2.4.1 i <value>
