Host Messaging and System
Configuration
The 4450 supports in-band and out-of-band host messaging for the purpose of system boot
and initialization, SPD & SAD management and exception handling, as well as IP packet
fragment reassembly.
5.1 Gigabit Ethernet & RMII Host Interfaces
The two Host side Gigabit Ethernet Interfaces (host 0 and host 1) can be configured for
either GMII/RGMII/SGMII/TBI/RTBI/SerDes signalling to accommodate data
communications between the host based MAC and the 4450. The interface signally options
for both host 0 and host 1 are configured to the same signalling option (i.e., GMII, RGMII,
etc.) for each host port. The Gigabit Ethernet Interfaces may also be used for in-band 4450
to host communications. The 4450 supports an additional RMII interface that can be used
for out-of-band host communications, messaging and management of the 4450. Figure 5-1
shows an example of the 4450 system connections.
