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.
Table 1: Performance per SIB/FPC Configuration
Number of Active SIBs | FPC Type and Number of PICs per FPC | Performance |
|---|---|---|
1 | FPC1 with up to four PICs | Line rate |
FPC2 with up to two PICs (except when both PICs are 4-port GE PICs) | Line rate | |
FPC2 with two 4-port GE PICs | Line rate not guaranteed | |
FPC2 with three or four PICs | Line rate not guaranteed | |
FPC3 with one or two PICs | Line rate not guaranteed | |
2 | FPC1 with up to four PICs | Line rate |
FPC2 with up to four PICs (except when all PICS are 4-port GE PICs) | Line rate | |
FPC2 with four 4-port GE PICs | Line rate not guaranteed | |
FPC2 with three 4-port GE PICs | Line rate | |
FPC3 with two PICs | Line rate not guaranteed | |
FPC3 with one PIC | Line rate | |
3 | FPC1 with up to four PICs | Line rate |
FPC2 with up to four PICs | Line rate | |
FPC3 with two PICs | Line rate not guaranteed | |
