Passive Monitoring on Ethernet Interfaces Overview

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:

  • 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

Note:

The PICs in the preceding list support only IPv4.

Note:

Starting with Junos OS Release 9.5, I2.0 based M120 routers and I3.0 based M320 routers with the PICs in the preceding list support passive monitoring. Other M Series and T Series routers with the PICs listed above started supporting passive monitoring before Junos OS Release 7.3. Support for 1-port 10-Gigabit Ethernet PIC with XENPAK on I2.0-based M120 routers and I3.0-based M320 routers was added in Junos OS Release 9.5.

  • 4-port 10-Gigabit Ethernet LAN/WAN PIC with XFP (T640, T1600, and T4000 Core Routers) (supported on both WAN-PHY and LAN-PHY modes for both IPv4 and IPv6 addresses)

The following interfaces support passive monitoring on the I3.0-based MX 240, MX 480, and MX 960 routers, starting with Junos OS Release 8.5:

  • 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.

Interfaces configured on the following FPCs and PIC support IPv6 passive monitoring on the T640, T1600, and T4000 routers:

  • Enhanced Scaling FPC2

  • Enhanced Scaling FPC3

  • Enhanced Scaling FPC4

  • Enhanced Scaling FPC4.1

  • Enhanced II FPC1 (T640 and T1600 routers)

  • Enhanced II FPC2 (T640 and T1600 routers)

  • Enhanced II FPC3 (T640 and T1600 routers)

  • 4-port 10-Gigabit Ethernet LAN/WAN PIC with XFP (supported on both WAN-PHY and LAN-PHY modes for both IPv4 and IPv6 addresses)

  • Gigabit Ethernet PIC with SFP

  • 10-Gigabit Ethernet PIC with XENPAK (T640 and T1600 routers)

  • SONET/SDH OC192/STM64 PICs with XFP (T1600 and T4000 routers)

  • SONET/SDH OC48c/STM16 PIC with SFP

  • SONET/SDH OC12/STM4 (Multi-Rate) PIC with SFP (T1600 router)

  • Type 1 SONET/SDH OC3/STM1 (Multi-Rate) PIC with SFP (T1600 router)

Note:

Unlike IPv4 passive monitoring, IPv6 passive monitoring is not supported on Monitoring Services PICs. You must configure port mirroring to forward the packets from the passive monitored ports to other interfaces.
