74 Using the RACADM Command Line Interface
Configuring the Network LAN Settings
NOTE: To perform the following steps, you must have Chassis Configuration
Administrator privilege.
NOTE: The LAN settings, such as community string and SMTP server IP address,
affect both the CMC and the external settings of the chassis.
NOTE: If you have two CMCs (primary and standby) on the chassis, and they are
both connected to the network, the standby CMC automatically assumes the
network settings in the event of failover of the primary CMC.
Enabling the CMC NIC
To enable the CMC NIC, type:
racadm config -g cfgLanNetworking -o cfgNicEnable 1
Enabling or Disabling DCHP for the NIC Address
When enabled, the CMC’s DHCP for NIC address feature requests and
obtains an IP address from the Dynamic Host Configuration Protocol
(DHCP) server automatically. This feature is enabled by default.
You can disable the DHCP for NIC address feature and specify a static IP
address, subnet mask, and gateway. For instructions, see "Setting Up Initial
Access to the CMC" on page 72.
NOTE: If you disable the DHCP for NIC address feature and then re-enable it later,
the static IP address, subnet mask, and gateway settings are lost.
Enabling or Disabling DHCP for DNS IP Addresses
By default, the CMC’s DHCP for DNS address feature is disabled. When
enabled, this feature obtains the primary and secondary DNS server addresses
from the DHCP server. Using this feature, you do not have to configure static
DNS server IP addresses.
To disable the DHCP for DNS address feature and specify static preferred and
alternate DNS server addresses, type:
racadm config -g cfgLanNetworking -o
cfgDNSServersFromDHCP
