Monitoring Redundant SIBs

You monitor and maintain redundant Switch Interface Boards (SIBs) installed in the M320 and T320 routers and the T640 Internet routing node 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 115 provides a checklist of tasks for you to perform to monitor redundant SIBs.
