cadAgingArpCacheNotPresentMaxNumber
Module: CADANT-CMTS-LAYER2CMTS-MIB
OID (symbolic): CADANT-CMTS-LAYER2CMTS-MIB::cadAgingArpCacheNotPresentMaxNumber
OID (numeric): 1.3.6.1.4.1.4998.1.1.20.1.2.9
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The maximum number of ICMP unreachables transmitted while an ARP cache entry is in the notPresent state. When the number of ICMPs indicated by this variable have been transmitted, the next packet that arrives for an ARP cache entry in the notPresent state will cause that entry to transition to the searching state, unless cadAgingArpCacheNotPresentMinTime has not been reached yet.
What is cadAgingArpCacheNotPresentMaxNumber?
This object sets the maximum number of ICMP unreachable messages the system can send for an ARP entry in the notPresent state before the entry transitions to searching. It prevents excessive control traffic when an ARP resolution repeatedly fails.
