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>
Configuring DNS Settings (IPv4 and IPv6)
• 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 specified then the maximum number of characters is 63. If
a domain name is specified 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.
Configuring Auto Negotiation, Duplex Mode, and Network Speed (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:
