Configuring 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. 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 cfgNetTuningNicAutoneg 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).
