Figure 6-1: Ethernet Switching Interface Diagram
Note: The phyiscal port numbering starts at 1, as indicated in the figure. However, the software port numbering
starts at 0. Therefore, to issue a command to a port, you must subtract 1 from the port numbers shown in the
figure.
Ethernet Transceivers
The BCM5461S is a 10/100/1000BASE-T GbE Ethernet transceiver using the SGMII interface.
The BCM5482 consists of two complete 10/100/1000BASE-T GbE transceivers supporting
both voice and data simultaneously.
