    SIB Overview

    Inspect the SIBs to ensure that they provide the switching function to the destination FPCs.

    A SIB forwards packets to a destination FPC.

    Table 1 shows the SIB characteristics for the M320 router, T320 router, T640 router, T1600 router, TX Matrix router, and TX Matrix Plus router.
