How Passive Monitoring works on Ethernet Interfaces

SUMMARY Learn about how Monitoring Services I and II PICs enable passive monitoring of IPv4 traffic on various Ethernet interfaces across MX Series routers.

The Monitoring Services I and Monitoring Services II PICs are designed to enable IP services. You can monitor IPv4 traffic if you have a Monitoring Services PIC installed in the router with the following PICs that support only IPv4.

  • 10-port Gigabit Ethernet PIC with SFPs

  • 4-port Gigabit Ethernet PIC with SFPs

  • 2-port Gigabit Ethernet PIC with SFPs

  • 1-port 10-Gigabit Ethernet PIC

The following interfaces support passive monitoring on the I3.0-based MX 240, MX 480, and MX 960 routers.

  • Type 2 MX FPCs

  • Type 3 MX FPCs

  • Gigabit Ethernet Enhanced DPC with SFP (DPCE-R-40GE-SFP)

  • 4-port 10-Gigabit Ethernet Enhanced DPCs with XFP (DPCE-R-4XGE-XFP)

The following interfaces support passive monitoring on the Trio-based MX 240, MX 480, and MX 960 routers:

  • 10-Gigabit Ethernet MPC with SFP+

  • 30-Gigabit Ethernet MPC

  • 60-Gigabit Ethernet MPC

Passive monitoring is also supported on MX 80 routers with 10-Gigabit Ethernet MPC with SFP+ and 30-Gigabit Ethernet MPC interfaces.
