Interpret the Enterprise-Specific Passive Monitoring MIB
The passive monitoring MIB, whose object identifier is
{jnxMibs 19},performs traffic flow monitoring and lawful interception of packets transiting between two routers. This MIB allows you to do the following:
- Gather and export detailed information about IPv4 traffic flows between source and destination nodes in your network.
- Sample all incoming IPv4 traffic on the monitoring interface and present the data in cflowd record format.
- Encrypt or tunnel outgoing cflowd records, intercepted IPv4 traffic, or both.
- Direct filtered traffic to different packet analyzers and present the data in its original format.
- The passive monitoring MIB has three tables:
jnxPMonFlowTable, JnxPMonErrorTable,andjnxPMonMemoryTable.jnxPMonFlowTablemonitors and collects statistics on the flow of traffic on a Passive Monitoring PIC.jnxPMonErrorTablemonitors and collects statistics on packet and memory errors on a Passive Monitoring PIC.jnxPMonMemoryTablemonitors and collects statistics on memory usage on a Passive Monitoring PIC. For information about system requirements, see the JUNOS Internet Software Feature Guide. For information about passive monitoring traps, seePassive Monitoring Overload Interface Version 2 Traps.
