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 >
where <
mtu > is a value between 576–1500 (inclusive; default is 1500).
