4.2.1 IPv4 and MAC Addresses

The 10 GB C&C Card has programmable MAC addresses and

programmable IPv4 addresses.

The MAC addresses can be set using the SETMAC instruction. The

device supports three modes of setting the MAC address:

 In Factory Default mode the MAC Address is the factory default.

 In Static mode the user can freely set the MAC address.

 In CW Auto mode the device automatically computes the MAC address

from its IP address (Figure 2). The first two bytes of the MAC address

are constant 42:57 hexadecimal. The lower 4 bytes refer to the IPv4

address.

Figure 2. CW Auto MAC Mode

The IP addresses can be configured with the SETIPV4 instruction. Both

Static IP and DHCP mode is supported. Note that the Internet Assigned

Numbers Authority (IANA) has reserved the following three blocks of the IP

address space for private networks (see RFC 1918):
