Module: CADANT-CMTS-LAYER2CMTS-MIB
OID (symbolic): CADANT-CMTS-LAYER2CMTS-MIB::cadAgingArpCacheSearchingCableBroadcast
OID (numeric): 1.3.6.1.4.1.4998.1.1.20.1.2.24
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: This variable controls whether broadcast ARP packets can be sent for an IPv4 address where there is no stored previous knowledge about a MAC/IP binding. The total number of broadcast ARPs to send before switching to the not-present state is limited by the cadAgingArpCacheSearchingMaxNumber variable. If cadAgingArpCacheSearchingCableBroadcast is false and there is no stored previous knowledge about a MAC/IP binding, the ARP cache entry will transition immediately to the not-present state.
What is cadAgingArpCacheSearchingCableBroadcast?
Controls whether the CMTS is allowed to send broadcast ARP packets on the cable interface when no prior MAC/IP binding is known for an IPv4 address. When enabled, the CMTS will attempt to discover the binding by broadcasting ARP requests, up to the configured limit, before marking the address as not-present.
