Hardware

Chassis

• In Junos OS Release 21.4R1, the MX10008 supports MX10K-LC9600, which is a fixed-port line card. However, the router supports the line card only if it also has the Switch Fabric Board SFB2 installed. The Joule fan trays and the Joule PSMs are required for SFB2 and MX10K-LC9600 support. Hyper mode is a default mode for SFB2 and MX10K-LC9600 line card.

  [See Fabric-Plane-Management-on-MX10008-Devices.]

• In Junos OS Release 21.4R1, the Switch Fabric Board SFB2 on the MX10008 router supports the MX10K-LC2101, MX10K-LC480, and MX10K-LC9600 line cards. The Joule fan trays and the Joule PSMs are required for SFB2 and MX10K-LC9600 support. Hyper mode is a default mode for SFB2 and MX10K-LC9600 line card. No fabric redundancy is supported with MX10K-LC9600. For MX10K-LC2101 and MX10K-LC480 line cards, 5+1 SFB2 fabric redundancy is provided.

Interfaces

• Interface support—MX10K-LC9600 is a fixed-port line card that can deliver a bandwidth of up to 9.6 Tbps. MX10K-LC9600 interoperates with existing MX Series line cards, such as MX10K-LC2101 and MX10K-LC480. The MX10K-LC9600 supports 12 Packet Forwarding Engines, each providing a maximum bandwidth of up to 800 Gbps. The line card supports six PICs, with four ports per PIC.

  Each port supports 10-Gbps, 25-Gbps, 40-Gbps, 100-Gbps, and 400-Gbps interface speeds using different optics.

  You can channelize the interfaces as follows:

  • Four 10 GbE interfaces
  • Four 25 GbE interfaces
  • Two 100 GbE interfaces
  • Four 100 GbE interfaces

  You can configure the port speed at the [edit chassis] hierarchy level.
