Interpreting the Enterprise-Specific Passive Monitoring MIB

[Contents] [Prev] [Next] [Index] [Report an Error]

The enterprise-specific 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 Internet Protocol version 4 (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, and jnxPMonMemoryTable. jnxPMonFlowTable monitors and collects statistics on the flow of traffic on a Passive Monitoring Physical Interface Card (PIC). jnxPMonErrorTable monitors and collects statistics on packet and memory errors on a Passive Monitoring PIC. jnxPMonMemoryTable monitors and collects statistics on memory usage on a Passive Monitoring PIC. For information about system requirements, see the JUNOS Feature Guide. For a downloadable version of this MIB, see www.juniper.net/techpubs/software/junos/junos94/swconfig-net-mgmt/mib-jnx-pmon.txt.
