NOTE: Note the following:
• There is a 30 seconds delay between changing a network setting and actually applying it.
• The CMC IPv6 addressing is disabled by default.
By default, for IPv4, the CMC requests and automatically obtains a CMC IP address from the Dynamic
Host Configuration Protocol (DHCP) server. You can disable the DHCP feature and specify static CMC IP
address, gateway, and subnet mask.
For an IPv4 network, to disable DHCP and specify static CMC IP address, gateway, and subnet mask, type:
racadm config -g cfgLanNetworking -o cfgNicUseDHCP 0
racadm config -g cfgLanNetworking -o cfgNicIpAddress <static IP address>
racadm config -g cfgLanNetworking -o cfgNicGateway <static gateway>
racadm config -g cfgLanNetworking -o cfgNicNetmask <static subnet mask>
By default, for IPv6, the CMC requests and automatically obtains a CMC IP address from the IPv6
autoconfiguration mechanism.
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 DHCP for the CMC Network Interface 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 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. While using this feature, you do not
have to configure static DNS server IP addresses.
To disable the DHCP for DNS address feature and specify the static preferred and alternate DNS server
addresses, type:
racadm config -g cfgLanNetworking -o
cfgDNSServersFromDHCP 0
To disable the DHCP for DNS address feature for IPv6 and specify the static preferred and alternate DNS
server addresses, type:
racadm config -g cfgIPv6LanNetworking -o
cfgIPv6DNSServersFromDHCP6 0
