cNatCgnCounterPortUsageClearHighThreshold

Module: CISCO-NAT-CGN-EXT-MIB

OID (symbolic): CISCO-NAT-CGN-EXT-MIB::cNatCgnCounterPortUsageClearHighThreshold

OID (numeric): 1.3.6.1.4.1.9.9.818.1.2.1.1.16

Node type: OBJECT-TYPE

Type: Integer32

Access: read-write

Description: This object specifies the clear high threshold in percentage of available public ports that are used up. The notification cNatCgnNotifPortUsageWatermarkHighClear 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.

Implementations must ensure that values of objects cNatCgnCounterPortUsageClearHighThreshold and cNatCgnCounterPortUsageHighThreshold remain consistent. For example, an implementation must respond with an inconsistentValue error if an attempt is made to set the the value of cNatCgnCounterPortUsageClearHighThreshold to be more than or equal to that of cNatCgnCounterPortUsageHighThreshold and vice versa.

What is cNatCgnCounterPortUsageClearHighThreshold?

A configurable percentage threshold that clears the high port-usage alarm once average port allocation falls back to or below this value, triggering a watermark-high-clear notification.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.818.1.2.1.1.16
snmpwalk -v2c -c public <target> CISCO-NAT-CGN-EXT-MIB::cNatCgnCounterPortUsageClearHighThreshold

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.818.1.2.1.1.16.1
snmpget -v2c -c public <target> CISCO-NAT-CGN-EXT-MIB::cNatCgnCounterPortUsageClearHighThreshold.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.9.9.818.1.2.1.1.16.1 i <value>
