Enabling the CMC Network Interface

To enable or disable the CMC network interface for both IPv4 and IPv6, type: 
racadm config -g cfgLanNetworking -o cfgNicEnable 1
                                 racadm config -g cfgLanNetworking -o cfgNicEnable 0
  • NOTE: The CMC NIC is enabled by default.
To enable or disable the CMC IPv4 addressing, type: 
racadm config -g cfgLanNetworking -o cfgNicIPv4Enable
                                    1
                                    racadm config -g cfgLanNetworking -o cfgNicIPv4Enable
                                    0
  • NOTE: The CMC IPv4 addressing is enabled by default.
To enable or disable the CMC IPv6 addressing, type: 
racadm config -g cfgIpv6LanNetworking -o cfgIPv6Enable
                                    1
                                    racadm config -g cfgIpv6LanNetworking -o cfgIPv6Enable
                                    0
  • 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>
