cadAgingNDCacheNotPresentMaxTime
Module: CADANT-CMTS-LAYER2CMTS-MIB
OID (symbolic): CADANT-CMTS-LAYER2CMTS-MIB::cadAgingNDCacheNotPresentMaxTime
OID (numeric): 1.3.6.1.4.1.4998.1.1.20.1.2.19
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The maximum amount of time an ND cache entry is in the notPresent state. When the amount of time indicated by this variable has elapsed, 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 cadAgingNDCacheNotPresentMaxTime?
This object specifies the maximum duration (in seconds) that an IPv6 neighbor discovery cache entry can remain in the 'not present' state before being forced to move to the 'searching' state. It controls how long the CMTS will hold an unresolved MAC/IPv6 address entry before re-querying. An operator would configure this value to tune the balance between reducing redundant neighbor discovery queries and responsiveness to network topology changes.
