86 Using the RACADM Command Line Interface
Removing a Server VLAN
To remove a server VLAN, disable the VLAN capabilities of the specified
server's network:
racadm setniccfg -m server-<n> -v
The valid values for <n> are 1-16.
For example:
racadm setniccfg -m server-1 -v
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 <mtu>
where <mtu> is a value between 576–1500 (inclusive; default is 1500).
NOTE: IPv6 requires a minimum MTU of 1280. If IPv6 is enabled, and
cfgNetTuningMtu is set to a lower value, the CMC uses an MTU of 1280.
Setting the SMTP Server IP Address (IPv4 and IPv6)
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
cfgRhostsSmtpServerIpAddr <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 is a duration when
this property setting does not work due to change in the specified SMTP server IP
address. In such cases, use the DNS name.
Configuring the Network Security Settings (IPv4 Only)
NOTE: To perform the following steps, you must have Chassis Configuration
Administrator privilege.
