Sun Microsystems CP3240 manual Switch Components, Broadcom StrataXGS 3 BCM56503 Ethernet Switch

2.2Switch Components

The following sections list and describe key components of the Sun Netra CP3240 switch.

2.2.1Broadcom StrataXGS 3 BCM56503 Ethernet Switch

The Sun Netra CP3240 switch uses Broadcom StrataXGS 3 BCM56503 for Base Ethernet switching/routing. This chip is an Ethernet switch with 24 1Gigabyte ports and 3 10Gigabyte ports. It provides non-blocking, wire-speed switching and routing on all ports under 100% load. The BCM56503 features many advanced features presented to the user via the FASTPATH software. See the Section 4.10, “FASTPATH” on page 4-18for more information.

2.2.2Broadcom StrataXGS 3 BCM56800 Ethernet Switch

The Sun Netra CP3240 switch uses Broadcom StrataXGS 3 BCM56800 for Fabric Ethernet switching/routing. This chip is an Ethernet switch with 20 10Gigabyte ports. It provides non-blocking, wire-speed switching and routing on all ports under 100% load. The BCM56800 features many advanced features presented to the user via the FASTPATH software. See Section 4.10, “FASTPATH” on page 4-18for more information.

2.2.3Broadcom BCM5464R and BCM5461S 10/100/1000Base-T Ethernet PHY

Quad and single ports respectively, the Broadcom PHYs provide the physical interfacing for 10/100/1000Base-T. They are low-power devices and provide features such as jumbo frames support, auto-MDIX, and cable testing.
