5.6.27 IPv4 Address (Words 15h - 16h
1
and 25h - 26h)
The following table lists the initial values for the IPv4 addresses.
Note: Since the 82546GB/EB is a dual-port device, the IPv4 Address in 15h-16h corresponds to LAN B,
and the IPv4 Address in 25h-26h corresponds to LAN A.
5.6.28 IPv6 Address (words 17h - 1Eh
1
and 27h - 2Eh)
The following table lists the initial values for the IPv6 addresses.
Note: Since the 82546GB/EB is a dual-port device, the IPv6 Address in 17h-1Eh corresponds to LAN B,
and the IPv6 Address in 27h-2Eh corresponds to LAN A.
1. Applicable to the 82546GB/EB only.
