Multiservices MIC and Multiservices MPC (MS-MIC and MS-MPC) Overview

 

Juniper Networks supports the Multiservices Modular Interfaces Card (MS-MIC) and the Multiservices Modular PIC Concentrator (MS-MPC) that provide improved scaling and high performance. The MS-MIC and MS-MPC have enhanced memory (16 GB for MS-MIC, 32 GB per NPU of MS-MPC) and processing capabilities.

The services interfaces on MS-MPC and MS-MIC are identified in the configuration with an ms- prefix (for example, ms-1/2/1). The following services packages come preinstalled and preconfigured on MS-MICs and MS-MPCs:

  • Junos Traffic Vision (formerly referred to as Jflow)

  • Junos Address Aware (formerly referred to as NAT features)

  • Junos VPN Site Secure (formerly referred to as IPsec features)

  • Junos Network Secure (formerly referred to as the Stateful Firewall feature)

  • Junos Services Crypto Base PIC Package

  • Junos Services Application Level Gateways

Note

You can check the default packages on an MS-MIC or MS-MPC by executing the show extension-provider system packages interface ms-interace operational mode command.

The MS-MPC on your MX Series router supports a maximum of two million active routes only. If the number of active routes exceeds this threshold, the heap memory used by the Packet Forwarding Engine is exhausted. As a result, the MS-MPC becomes unresponsive.

The MS-MIC supports the following Layer 3 services such as stateful firewall, NAT, IPsec, active flow monitoring, RPM, and graceful Routing Engine switchover (GRES). For more information on the supported features, see Protocols and Applications Supported by the MS-MIC and MS-MPC.

The MS-MIC and MS-MPC also support the captive portal content delivery (HTTP redirect) service package when configured for installation using the set chassis operational mode command.

Note
  • Starting with Junos OS Release 14.2, the MX104 router supports two MS-MICs. Also, graceful Routing Engine switchover (GRES) is not supported for MS-MIC on the MX104 router.

  • Starting from Junos OS Release 18.1R1, Junos Node Slicing supports assignment of MS-MICs and MS-MPCs to guest network functions (GNFs), or partitions created on a router by using Junos Node Slicing.

  • Starting with Junos OS Release 19.2R1, the MX2020 router supports 15 MS-MPC cards.
