arpEntryTimeout
Module: COMPEX-IN3000
OID (symbolic): COMPEX-IN3000::arpEntryTimeout
OID (numeric): 1.3.6.1.4.1.426.1.11.9
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The length of time (in seconds) that an ARP entry is stored. If an entry is not accessed within this time period the entry is purged.
Changes to this take place immediately.
What is arpEntryTimeout?
This read-write integer, ranging from 15 to 60480 seconds, sets how long an ARP cache entry is retained before being purged if it is not accessed again, with changes taking effect immediately. An admin shortens this value to make the device react faster to hosts changing IP-to-MAC mappings, or lengthens it to reduce ARP traffic churn on a stable network. Seeing arpDeadEntries climb too fast would lead an admin to raise arpEntryTimeout so stable entries are not purged prematurely.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.426.1.11.9 snmpwalk -v2c -c public <target> COMPEX-IN3000::arpEntryTimeout
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.426.1.11.9.1 snmpget -v2c -c public <target> COMPEX-IN3000::arpEntryTimeout.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.426.1.11.9.1 i <value>
