MX2000 Switch Fabric Board (SFB) Overview

 

Switch Fabric Boards (SFBs) are the data plane for the subsystems in the MX router chassis. SFBs create a highly scalable and resilient “all-active” centralized switch fabric that delivers up to 4 Tbps of full-duplex switching capacity to each MPC slot in an MX2000 router.

There are three models of MX SFBs:

The SFB and SFB2 switch fabric board models are the same except that the SFB model has three XF fabric chips per card whereas the SFB2 model has two PF fabric chips per card.
