cadAgingArpCacheSearchingCableUnicast
Module: CADANT-CMTS-LAYER2CMTS-MIB
OID (symbolic): CADANT-CMTS-LAYER2CMTS-MIB::cadAgingArpCacheSearchingCableUnicast
OID (numeric): 1.3.6.1.4.1.4998.1.1.20.1.2.23
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The maximum number of unicast ARP requests transmitted while an ARP cache entry is in the searching state where the MAC/IP binding is previously known. After the number of unicast ARPs indicated by this variable have been transmitted, additional ARP requests will be sent as broadcast until the cadAgingArpCacheSearchingMaxNumber limit is reached, at which point the next packet that arrives for an ARP cache entry in the searching state will cause that entry to transition to the notPresent state.
What is cadAgingArpCacheSearchingCableUnicast?
Controls ARP cache behavior for unicast traffic on the cable interface while an ARP entry is in the searching state. This configurable parameter likely governs whether ARP requests for cable-side hosts are sent as unicast rather than broadcast during address resolution.
