6.10.3.3 IPV6 Support
In addition to IPv4, the server board has support for IPV6 for manageability channels.
Configuration of IPv6 is provided by extensions to the IPMI Set and Get LAN Configuration
Parameters commands as well as through a Web Console IPv6 configuration web page.
The BMC supports IPv4 and IPv6 simultaneously so they are both configured separately and
completely independently. For example, IPv4 can be DHCP configured while IPv6 is statically
configured or vice versa.
The parameters for IPv6 are similar to the parameters for IPv4 with the following differences:
An IPv6 address is 16 bytes vs. 4 bytes for IPv4.
An IPv6 prefix is 0 to 128 bits whereas IPv4 has a 4 byte subnet mask.
There are two variants of automatic IP Address Source configuration vs. just DHCP for IPv4.
The three possible IPv6 IP Address Sources for configuring the BMC are:
Static (Manual): The IP, Prefix, and Gateway parameters are manually configured by the user.
The BMC ignores any Router Advertisement messages received over the network.
DHCPv6: The IP comes from running a DHCPv6 client on the BMC and receiving the IP from a
DHCPv6 server somewhere on the network. The Prefix and Gateway are configured by Router
Advertisements from the local router. The IP, Prefix, and Gateway are read-only parameters to
the BMC user in this mode.
Static (Manual): The IP, Prefix, and Gateway parameters are manually configured by the user.
The BMC ignores any Router Advertisement messages received over the network.
DHCPv6: The IP comes from running a DHCPv6 client on the BMC and receiving the IP from a
DHCPv6 server somewhere on the network. The Prefix and Gateway are configured by Router
Advertisements from the local router. The IP, Prefix, and Gateway are read-only parameters to
the BMC user in this mode.
Stateless auto-config: The Prefix and Gateway are configured by the router through Router
Advertisements. The BMC derives its IP in two parts: the upper network portion comes from the
router and the lower unique portion comes from the BMC's channel MAC address. The 6-byte
MAC address is converted into a 8-byte value per the EUI-64* standard. For example, a MAC
value of 00:15:17:fe:2f:62 converts into a EUI-64 value of 215:17ff:fefe:2f62. If the BMC
receives a Router Advertisement from a router at IP 1:2:3:4::1 with a prefix of 64, it would then
generate for itself an IP of 1:2:3:4:215:17ff:fefe:2f62. The IP, Prefix, and Gateway are read-only
parameters to the BMC user in this mode.
IPv6 can be used with the BMC's Web Console, JViewer (remote KVM and Media), and
