Enable Passive Monitoring

The Passive Monitoring PIC is one of a group of multiservice PICs designed to enable IP services. If you have Passive Monitoring PICs and SONET/SDH PICs installed in an M160 or M40e router, you can monitor IPv4 traffic from another router.

Passive Monitoring PICs must be mounted on an enhanced FPC.

On SONET interfaces, you enable packet flow monitoring by including the passive-monitor-mode statement at the [edit interfaces so-fpc/pic/port unit logical-unit-number] hierarchy level:

[edit interfaces so-fpc/pic/port unit logical-unit-number] 

passive-monitor-mode;

If you include the passive-monitor-mode statement in the configuration, the SONET interface does not send keepalives or alarms, and does not participate actively on the network.

On passive monitoring interfaces, you enable packet flow monitoring by including the family statement at the [edit interfaces mo-fpc/pic/port unit logical-unit-number] hierarchy level, specifying the inet option:

[edit interfaces mo-fpc/pic/port unit logical-unit-number] 

family inet;

For the passive monitoring interface, you can configure multiservice physical interface properties. For more information, see Configure Multiservice Physical Interface Properties.
