Queuing Parameters for the Router Hardware, PIC, MIC, and MPC Interface Families

Table 1 compares the PIC, MIC, and MPC interface families with regard to queuing parameters and features. In this table, the OSE PICs refer to the 10-port 10-Gigabit OSE PICs (described in some guides as the 10-Gigabit Ethernet LAN/WAN PICs with SFP+).
