Cavium ProcessorComplex: Cavium Ethernet

CAVIUM ETHERNET

The Ethernet address for your board is a unique identifier on a network. The address con- sists of 48 bits (MAC [47:0]) divided into two equal parts. The upper 24 bits define a unique identifier that has been assigned to Emerson Network Power, Embedded Computing by IEEE. The lower 24 bits are defined by Emerson for identification of each of our products.

The Ethernet address for the ATCA-9305 is a binary number referenced as 12 hexadecimal digits separated into pairs, with each pair representing eight bits. The address assigned to the ATCA-9305 has the following form:

00 80 F9 xx yy zz

00 80 F9 is Emerson’s identifier. The last three bytes of the Ethernet address consist of the port (one byte); 0x99(SPI 1), 0x9A (SPI 2), 0x9B (SPI 3), or 0x9C (SPI 4), followed by the serial number (two byte hexadecimal). The ATCA-9305 Cavium has been assigned the Ethernet address range 00:80:F9:99:00:00 to 00:80:F9:9C:FF:FF. The format is shown in Table 3-3.

The last two bytes, MAC[15:0], are calculated from the serial number stored in the Cavium EEPROM. This corresponds to the following formula: n —1000, where n is the unique serial number assigned to each board. So if an ATCA-9305 serial number is 1032, the calculated value is 32 (2016), and the default Ethernet port addresses are:

•Cavium 1 SPI 1 MAC address is: 0x00 0x80 0xF9 0x99 0x00 0x20

•Cavium 1 SPI 2 MAC address is: 0x00 0x80 0xF9 0x9A 0x00 0x20

•Cavium 2 SPI 1 MAC address is: 0x00 0x80 0xF9 0x9B 0x00 0x20

•Cavium 2 SPI 2 MAC address is: 0x00 0x80 0xF9 0x9C 0x00 0x20
