76 Using the RACADM Command Line Interface
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>
racadm config -g cfgNetTuning -o cfgNetTuningNicSpeed <speed>
where:
•< duplex mode > is 0 (half duplex) or 1 (full duplex, default)
•<
speed > is 10, 100 or 1000 (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).
Setting the SMTP Server IP Address
You can enable the CMC to send e-mail alerts using Simple Mail Transfer
Protocol (SMTP) to a specified IP address. To enable this feature, type:
racadm config -g cfgRemoteHosts -o
cfgRhostsFwUpdateIpAddr <
SMTP IP address >
where <
SMTP IP address > is the IP address of the network SMTP server.
NOTE: If your network has an SMTP server that releases and renews IP address
leases periodically, and the addresses are different, then there will be a duration
when this property setting will not work due to change in the specified SMTP server
IP address. In such cases, use the DNS name.
