74 Using the RACADM Command Line Interface
• 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; the name must begin with a letter. 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 <name>
where < name > is a string of up to 254 alphanumeric characters and
hyphens; the DNS domain name must begin with a letter. For example:
p45, a-tz-1, r-id-001.
Configuring Auto Negotiation, Duplex Mode, and Network Speed
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. Auto negotiation is enabled by default.
You can disable auto negotiation and specify the duplex mode and network
speed by typing:
racadm config -g cfgNetTuning -o cfgNetTuningNicEnable 0
racadm config -g cfgNetTuning -o cfgNetTuningNicFullDuplex <duplex
mode>
where:
•< duplex mode > is 0 (half duplex) or 1 (full duplex, default)
racadm config -g cfgNetTuning -o cfgNetTuningNicSpeed <speed>
where:
•< speed > is 10 or 100(default).
Setting the Maximum Transmission Unit (MTU)
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 <mtu>
