Frequently Asked Questions

What is the difference between MPC3E-3D-NG and MPC3E-3D-NG-IR-B?

The MPC3E-3D-NG is the standard next-generation MPC3E for MX240/480/960, while the MPC3E-3D-NG-IR-B is a variant with IR (Integrated Routing) or enhanced buffer configuration. Both share the same MX chassis compatibility but differ in forwarding profile or buffer specifications for specific traffic engineering use cases.

How many MIC slots does the MPC3E-3D-NG provide?

The MPC3E-3D-NG provides 2 MIC slots, accepting standard MX-series MIC modules. Interface density and type depend entirely on the MICs installed — from 10GbE to 100GbE interfaces depending on MIC selection.

Is the MPC3E-3D-NG hot-pluggable in an active MX chassis?

Yes — MX-series MPCs including the MPC3E-3D-NG support online insertion and removal (OIR) for non-disruptive maintenance. Traffic on other MPCs in the chassis is not affected during MPC3E-3D-NG insertion or removal.

The Juniper MPC3E-3D-NG delivers next-generation forwarding performance and Junos 3D feature depth for MX240, MX480, and MX960 service provider deployments — providing the flexible MIC-based interface density and enhanced packet processing that high-scale core, edge, and BNG routing environments demand.
