Setting static DNS IP addresses
NOTE: The static DNS IP addresses settings are not valid unless the DCHP for DNS address feature is disabled.
For IPv4, to set the preferred primary and secondary DNS IP server addresses, type:
racadm config -g cfgLanNetworking -o cfgDNSServer1 <IP-address>
racadm config -g cfgLanNetworking -o cfgDNSServer2 <IPv4-address>
For IPv6, to set the preferred and secondary DNS IP Server addresses, type:
racadm config -g cfgIPv6LanNetworking -o
cfgIPv6DNSServer1 <IPv6-address>
racadm config -g cfgIPv6LanNetworking -o
cfgIPv6DNSServer2 <IPv6-address>
Viewing and modifying CMC network LAN settings
The LAN settings, such as community string and SMTP server IP address, aect both the CMC and the external settings of the
chassis.
When IPv6 is enabled at boot time, three router solicitations are sent after every four seconds. If external network switches are
running the Spanning Tree Protocol (STP), the external switch ports may be blocked for more than 12 seconds in which the IPv6
router solicitations are sent. In such cases, there may be a period when IPv6 connectivity is limited, until router advertisements are
gratuitously sent by the IPv6 routers.
NOTE: Changing the CMC network settings may disconnect your current network connection.
NOTE: You must have Chassis Conguration Administrator privilege to set up CMC network settings.
Viewing and modifying CMC network LAN settings using CMC web interface
To view and modify the CMC LAN network settings using CMC Web interface:
1. In the left pane, click Chassis Overview, and then click Network. The Network Conguration page displays the current
network settings.
2. Modify the general, IPv4, or IPv6 settings as required. For more information, see the Online Help.
3. Click Apply Changes for each section to apply the settings.
Viewing CMC network LAN settings using RACADM
To view IPv4 settings, use the object cfgCurrentLanNetworking with the following subcommands:
• getniccfg
• getconfig
To view IPv6 settings, use the cfgIpv6LanNetworking with the getconfig subcommand.
To view IPv4 and IPv6 addressing information for the chassis, use the getsysinfo subcommand.
For more information about the subcommands and objects, see the Chassis Management Controller for PowerEdge FX2/FX2s
RACADM Command Line Reference Guide.
Enabling CMC network interface
To enable or disable the CMC network interface for both IPv4 and IPv6, type:
racadm config -g cfgLanNetworking -o cfgNicEnable 1
racadm config -g cfgLanNetworking -o cfgNicEnable 0
