Checklist for Monitoring Redundant SIBs
Purpose You monitor and maintain redundant Switch Interface Boards (SIBs) installed in the
M320 and T320 routers and the T640 router to ensure that there is no interruption of
switching function to the destination Flexible PIC Concentrator (FPC). The SIBs create
the switch fabric, providing up to a total of 640 million packets per second (Mpps) of
forwarding.
Table 145 on page 649 provides a checklist of tasks for you to perform to monitor redundant
SIBs.
