M320 Performance for Different SIB Configurations

 

Table 1 describes expected performance per total active SIBs for different FPC and PIC configurations. The packet forwarding rate of each FPC is independent of the number and configuration of other FPCs in the chassis. The packet forwarding rate depends on the total number of PICs in the FPC, the number of active SIBs in the chassis, and packet size.
