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:

    If you disable CMC network interface, the disable operation performs the following actions:

    • Disables the network interface access to out-of-band chassis management, including iDRAC and IOM management.

    • Prevents the down link status detection.

      To disable only CMC network access, disable both CMC IPv4 and CMC IPv6.

  • 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: The CMC IPv6 addressing is disabled by default.
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, the DHCP is disabled. To enable DHCP and use the DHCP server on the network to assign iDRAC or CMC IPv4 address, subnet mask, and gateway, type: 

racadm config -g cfgLanNetworking -o cfgNicUseDHCP 1

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>
