Users Guide

To enable or disable the CMC IPv4 addressing, type:

racadm config -g cfgLanNetworking -o cfgNicIPv4Enable

NOTE: The CMC IPv4 addressing is enabled by default.

To enable or disable the CMC IPv6 addressing, type:

racadm config -g cfgIpv6LanNetworking -o cfgIPv6Enable

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

Conguration 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 autoconguration mechanism.

For an IPv6 network, to disable the Autoconguration feature and specify a static CMC IPv6 address, gateway, and prex 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 Conguration

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 congure static DNS server IP addresses.
