cadAgingNDCacheNotPresentMaxNumber
Module: CADANT-CMTS-LAYER2CMTS-MIB
OID (symbolic): CADANT-CMTS-LAYER2CMTS-MIB::cadAgingNDCacheNotPresentMaxNumber
OID (numeric): 1.3.6.1.4.1.4998.1.1.20.1.2.18
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The maximum number of ICMP unreachables transmitted while an ND 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 ND cache entry in the notPresent state will cause that entry to transition to the searching state, unless cadAgingNDCacheNotPresentMinTime has not been reached yet.
What is cadAgingNDCacheNotPresentMaxNumber?
This configuration parameter sets the maximum number of ICMP unreachable responses the system will send for a neighbor discovery cache entry in the notPresent state before transitioning it to searching state. It controls how aggressively the system probes for unreachable destinations to optimize network resource usage. Operators would adjust this value to balance between responsiveness to network changes and network load from probe traffic.
