Using the RACADM Command Line Interface 77
racadm config -g cfgLanNetworking -o cfgNicNetmask
<static subnet mask>
By default, for IPv6, the CMC requests and obtains a CMC IP address from
the IPv6 Autoconfiguration mechanism automatically.
For an IPv6 network, to disable the Autoconfiguration feature and specify a
static CMC IPv6 address, gateway, and prefix length, type:
racadm config -g cfgIPv6LanNetworking -o
cfgIPv6AutoConfig 0
racadm config -g cfgIPv6LanNetworking -o
cfgIPv6Address <IPv6 address>
racadm config -g cfgIPv6LanNetworking -o
cfgIPv6PrefixLength 64
racadm config -g cfgIPv6LanNetworking -o
cfgIPv6Gateway <IPv6 address>
Enabling or Disabling DCHP for the NIC Address
When enabled, the CMC’s DHCP for NIC address feature requests and
obtains an IP address from the Dynamic Host Configuration Protocol
(DHCP) server automatically. This feature is enabled by default.
You can disable the DHCP for NIC address feature and specify a static
IP address, subnet mask, and gateway. For more information, see "Setting Up
Initial Access to the CMC."
Enabling or Disabling DHCP for DNS IP Addresses
By default, the CMC’s DHCP for DNS address feature is disabled.
When enabled, this feature obtains the primary and secondary DNS server
addresses from the DHCP server. Using this feature, you do not have to
configure static DNS server IP addresses.
To disable the DHCP for DNS address feature and specify static preferred and
alternate DNS server addresses, type:
racadm config -g cfgLanNetworking -o
cfgDNSServersFromDHCP 0
