hm2AgentSwitchArpAgeoutTime
Module: HM2-PLATFORM-ROUTING-MIB
OID (symbolic): HM2-PLATFORM-ROUTING-MIB::hm2AgentSwitchArpAgeoutTime
OID (numeric): 1.3.6.1.4.1.248.12.2.1.1
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: HiOS: Configures the exact ARP entry age-out time in seconds. HiSecOS: Configures the average ARP entry age-out time in seconds, with each entry aging out after a random time between 0.5*hm2AgentSwitchArpAgeoutTime and 1.5*hm2AgentSwitchArpAgeoutTime.
What is hm2AgentSwitchArpAgeoutTime?
How long an ARP entry stays in the cache before it expires, in seconds (15 to 21600, default 1200). On HiOS it is the exact age-out time; on HiSecOS it is an average, with each entry expiring at a random point between half and one and a half times the value. Lower it when hosts change MAC addresses often, raise it to cut ARP traffic.
