cNatCgnCounterPortUsageLowThreshold
Module: CISCO-NAT-CGN-EXT-MIB
OID (symbolic): CISCO-NAT-CGN-EXT-MIB::cNatCgnCounterPortUsageLowThreshold
OID (numeric): 1.3.6.1.4.1.9.9.818.1.2.1.1.13
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: This object specifies the low threshold in percentage of available public ports that are used up. The notification cNatCgnNotifPortUsageWatermarkLow is sent once the value of cNatCgnCounterAveragePortAllocation becomes less than or equal to this value. If this object is set to zero, the notification is not generated.
What is cNatCgnCounterPortUsageLowThreshold?
A configurable low-watermark percentage of used public ports; when average port allocation drops to or below this value, the device sends a port-usage-low notification, letting operators detect when NAT port pressure has eased.
