Description

 

This article describes how to monitor CGNAT NAT Pool thresholds using SNMP. For CGNAT NAT pools, each PIC on an MultiServices Denser Port Concentrator (MS-DPC) card can support 8.1 million ports for NAT translation.

 

Monitoring Options

 

Use the JUNIPER-NAT-MIB to monitor the utilization of each MS-DPC card and PIC. This MIB identifies the current utilization of each PIC with regard to the number of ports consumed.

 

There are two ways to monitor the port utilization:

 

  • Use your NMS to poll the jnxNatSrcNumPortAvail MIB object to track the number of available ports and set a threshold on this value.
  • Use the MIB jnxNatAddrPoolUtil notification to receive an SNMP trap for the dynamic address pool utilization as a percentage.
