Users Guide

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 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>

Conguring IPv4 and IPv6 DNS settings

• CMC Registration — To register the CMC on the DNS server, type:

racadm config -g cfgLanNetworking -o

cfgDNSRegisterRac 1

NOTE: Some DNS servers only register names of 31 characters or fewer. Make sure the designated name is within the

DNS required limit.

NOTE: The following settings are valid only if you have registered the CMC on the DNS server by setting

cfgDNSRegisterRac to 1.

• CMC Name — By default, the CMC name on the DNS server is cmc-<service tag>. To change the CMC name on the DNS

server, type:

racadm config -g cfgLanNetworking -o cfgDNSRacName <name>

where < name > is a string of up to 63 alphanumeric characters and hyphens. For example: cmc-1, d-345.
