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 2 Tbps of full-duplex
switching capacity to each MPC slot in an MX2000 router.
There are three models of MX SFBs:
MX2000-SFB-S Description
MX2000-SFB2-S Enhanced Switch Fabric Board Description
MX2000-SFB3 Switch Fabric Board Description
The SFB and SFB2 switch control 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.
