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>
