cadAgingNDCacheNotPresentRateLimit
Module: CADANT-CMTS-LAYER2CMTS-MIB
OID (symbolic): CADANT-CMTS-LAYER2CMTS-MIB::cadAgingNDCacheNotPresentRateLimit
OID (numeric): 1.3.6.1.4.1.4998.1.1.20.1.2.17
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The minimum amount of time between transmitting ICMP unreachables while an ND cache entry is in the notPresent state.
What is cadAgingNDCacheNotPresentRateLimit?
This writable object specifies the minimum milliseconds (100 to 86,400,000) between ICMP Unreachable messages sent for an IPv6 Neighbor Discovery cache entry in the notPresent state, preventing flooding of unreachable notifications. Operators configure this to balance responsiveness (detect missing neighbors quickly) against network congestion and router CPU load when many neighbors are unreachable.
Examples
