Gigabit Ethernet (GMII) Configuration

Gigabit Ethernet Media Independent Interface (GMII) is configured in one of two ways:

• Use one CP cluster when density is more important than wire-speed performance

because you can then implement up to four Gigabit Ethernet ports per C-5e NP.

• Use two CP clusters for wire-speed performance and additional processing power. You

can implement up to two Gigabit Ethernet ports per C-5e NP.

Table 10 lists the possible CP cluster combinations you can use and Figure 4 shows receive

and transmit pin configurations by cluster. Table 11 lists the signals and pinouts for

Gigabit Ethernet (GMII).

CLUSTER

SINGLE CLUSTER MODE (TBI OR GMII)

TWO CLUSTER MODE (GMII)*

* The Two Cluster Mode column lists typical configurations. Any cluster can be set up to either receive

or transmit. So you could configure a dual cluster mode where cluster 0 receives and cluster 3

transmits.
