Monitoring the SIBs
Purpose You monitor the Switch Interface Boards (SIBs) that provide the switching function to
the destination Flexible PIC Concentrator (FPC). The SIBs create the switch fabric for
the routing platforms, providing up to a total of 640 million packets per second (Mpps)
of forwarding. (See Table 108 on page 413.)
