cadAgingNDCacheNotPresentMinTime
Module: CADANT-CMTS-LAYER2CMTS-MIB
OID (symbolic): CADANT-CMTS-LAYER2CMTS-MIB::cadAgingNDCacheNotPresentMinTime
OID (numeric): 1.3.6.1.4.1.4998.1.1.20.1.2.20
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description:
The minimum amount of time an ARP cache entry is in the notPresent state. This variable takes precedence over cadAgingArpCacheNotPresentMaxNumber and cadAgingArpCacheNotPresentMaxTime. However, and ARP entry aged out due to inactivity will be removed regardless of whether the amount of time indicated by cadAgingArpCacheNotPresentMinTime has elapsed or not.
What is cadAgingNDCacheNotPresentMinTime?
This configurable threshold (in seconds) specifies the minimum amount of time a neighboring device discovery (or ARP) cache entry must remain in the 'not present' state before the Cadant CMTS system removes it or takes other action. This parameter takes precedence over other aging timers and ensures that unresponsive entries are eventually cleared. Cable operators configure this to balance memory usage against the risk of prematurely forgetting legitimate neighbors.
