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 racadm config -g cfgLanNetworking -o cfgNicGateway racadm config -g cfgLanNetworking -o cfgNicNetmask 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 racadm config -g cfgIPv6LanNetworking -o cfgIPv6PrefixLength 64 racadm config -g cfgIPv6LanNetworking -o cfgIPv6Gateway 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 enable 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 enable 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 Setting Static DNS IP addresses NOTE: The static DNS IP addresses settings are not valid unless the DCHP for DNS address feature is disabled. For IPv4, to set the preferred primary and secondary DNS IP server addresses, type: racadm config -g cfgLanNetworking -o cfgDNSServer1 racadm config -g cfgLanNetworking -o cfgDNSServer2 65

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 enable 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 enable 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

Setting Static DNS IP addresses

NOTE:

The static DNS IP addresses settings are not valid unless the DCHP for DNS address feature is disabled.

For IPv4, to set the preferred primary and secondary DNS IP server addresses, type:

racadm config -g cfgLanNetworking -o cfgDNSServer1 <IP-address>

racadm config -g cfgLanNetworking -o cfgDNSServer2 <IPv4-address>
