To disable 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 disable 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>
For IPv6, to set the preferred and secondary DNS IP Server addresses, type:
racadm config -g cfgIPv6LanNetworking -o
cfgIPv6DNSServer1 <IPv6-address>
racadm config -g cfgIPv6LanNetworking -o
cfgIPv6DNSServer2 <IPv6-address>
Conguring 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 specied then the maximum number of characters is 63. If a domain name is specied
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.
Conguring 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.
