For IPv6, to set the preferred and secondary DNS IP Server addresses, type: racadm config -g cfgIPv6LanNetworking -o cfgIPv6DNSServer1 racadm config -g cfgIPv6LanNetworking -o cfgIPv6DNSServer2 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-. To change the CMC name on the DNS server, type: racadm config -g cfgLanNetworking -o cfgDNSRacName where is a string of up to 63 alphanumeric characters and hyphens. For example: cmc-1, d-345. • 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 where 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 where: is 0 (half duplex) or 1 (full duplex, default) racadm config -g cfgNetTuning -o cfgNetTuningNicSpeed where: is 10 or 100 (default). Setting the Maximum Transmission Unit (MTU) (IPv4 and IPv6) The MTU property allows you to set a limit for the largest packet that can be passed through the interface. To set the MTU, type: racadm config -g cfgNetTuning -o cfgNetTuningMtu where is a value between 576-1500 (inclusive; default is 1500). 66
