Software release

  • Junos OS releases 14.1R4, 14.2R3 and Junos Continuity, Junos OS release 15.1 and later.

  • Refer to MIC/MPC Compatibility for information about which MICs are supported on this MPC.

  • Refer to the JTAC Knowledgebase article for recommended software releases.


  • 130 Gbps capacity without hierarchical quality of service (HQoS)

  • Requires high-capacity fan trays and high-capacity filter trays

  • Weight: 15.96 lb (7.26 kg)

  • Model number: MPC3E-3D-NG

  • Name in the CLI: MPC3E NG PQ & Flex Q

  • Add-on license provides limited additional flexible queuing.

Hardware features

  • Line-rate throughput of up to 130 Gbps

  • Supports WAN-PHY mode at 9.95 Gbps and LAN-PHY mode at 10.31 Gbps

  • Supports maximum transmission unit (MTU) size of 9,192 bytes for host bound packets. For Junos OS 16.1R1 and later releases, the MTU size supported is 9,500 bytes.

  • Two slots for MICs

  • Junos Trio chipsets for increased scaling for bandwidth, subscribers, and services


The non-HQOS MPC3E NG and MPC2E NG MPCs support MIC-3D-8CHOC3-4CHOC12 and MIC-3D-4CHOC3-2CHOC12 only with a limited queuing license.


The MPC3E-3D-NG requires high-capacity power supplies, high-capacity fan trays, and enhanced switch control boards (SCBE, SCBE2, or SCBE3) on MX240, MX480, and MX960 routers.

Software features

  • Chained composite next hops

  • Layer 3 VPN localization

  • Detection of Layer 2 loops

  • Entropy label support in mixed mode

  • SNMP and CLI support for Routing Engine memory monitoring

  • Mixed Mode LAG support on core interfaces

  • Dynamic power management for MICs

  • Support for flexible-queuing

  • See Protocols and Applications Supported by the MPC3E on MX Series Routers for information about the protocols and applications that this MPC supports.

Power requirement

Maximum with highest-power MICs at 55° C: 11.13 A @ 48 V (534 W)

At different temperatures:

  • 55° C: 534 W

  • 40° C: 485 W

  • 25° C: 461 W


OK/FAIL LED, one bicolor:

  • Steady green—MPC is functioning normally.

  • Blinking green—MPC is transitioning online or offline.

  • Red—MPC has failed.


On the MX960 router, all the MPC slots work in a chassis temperature of up to 40°C (104°F), at an altitude of up to 6000 feet. However, when the chassis temperature exceeds 40°C (104°F),

  • the slot 11 does not work with MPC3E-3D-NG, MPC3E-3D-NG-Q, MPC4E, and MPC5E.

  • the slot 0 does not work with MPC4E and MPC5E.
