Enabling Or Disabling Dhcp For The Cmc Network Interface Address; Enabling Or Disabling Dhcp For Dns Ip Addresses; Setting Static Dns Ip Addresses - Dell PowerEdge VRTX User Manual

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>

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
Configuration 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 configure static
DNS server IP addresses.
To enable the DHCP for DNS address feature and specify the static preferred and alternate DNS server addresses, type:
racadm config -g cfgLanNetworking -o
cfgDNSServersFromDHCP 0
To enable the DHCP for DNS address feature for IPv6 and specify the static preferred and alternate DNS server
addresses, type:
racadm config -g cfgIPv6LanNetworking -o
cfgIPv6DNSServersFromDHCP6 0

Setting Static DNS IP addresses

NOTE: The static DNS IP addresses settings are not valid unless the DCHP for DNS address feature is disabled.
For IPv4, to set the preferred primary and secondary DNS IP server addresses, type:
racadm config -g cfgLanNetworking -o cfgDNSServer1 <IP-address>
racadm config -g cfgLanNetworking -o cfgDNSServer2 <IPv4-address>
