Users Guide

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.
NOTE
: If a DNS Domain name is not specied then the maximum number of characters is 63. If a domain name is specied
then the number of characters in CMC name plus the number of characters in the DNS Domain Name must be less than or
equal to 63 characters.
• DNS Domain Name — The default DNS domain name is a single blank character. To set a DNS domain name, type:
racadm config -g cfgLanNetworking -o
cfgDNSDomainName <name>
where < name > is a string of up to 254 alphanumeric characters and hyphens. For example: p45, a-tz-1, r-id-001.
Conguring auto negotiation, duplex mode, and
network speed for IPv4 and IPv6
When enabled, the auto negotiation feature determines whether the CMC automatically sets the duplex mode and network speed by
communicating with the nearest router or switch. By default, auto negotiation feature is enabled.
You can disable auto negotiation and specify the duplex mode and network speed by typing:
racadm config -g cfgNetTuning -o cfgNetTuningNicAutoneg 0
racadm config -g cfgNetTuning -o cfgNetTuningNicFullDuplex <duplex mode>
where:
