Configuring Multiple CMCs through RACADM Using Configuration File

Viewing and Modifying CMC Network LAN Settings

The LAN settings, such as community string and SMTP server IP address, affect both the CMC and the

external settings of the chassis.

If you have two CMCs (active and standby) on the chassis, and they are connected to the network, the

standby CMC automatically assumes the network settings of the active CMC in the event of failover.

When IPv6 is enabled at boot time, three router solicitations are sent every four seconds. If external

network switches are running the Spanning Tree Protocol (SPT), the external switch ports may be blocked

for more than twelve 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 Configuration 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 system tree, go to Chassis Overview and click Network → Network. The Network

Configuration page displays the current network settings.

2. Modify the general, IPv4 or IPv6 settings as required. For more information, see the CMC Online

Help.

3. Click Apply Changes for each section to apply the settings.

Viewing and Modifying CMC Network LAN Settings Using RACADM

Use the command getconfig -g cfgcurrentlannetworking to view IPv4 settings.

Use the command getconfig -g cfgCurrentIPv6LanNetworking to view IPv6 settings.

To view IPv4 and IPv6 addressing information for the chassis, use getsysinfo subcommand.

For more information about the subcommands and objects, see the Chassis Management Controller for

Dell PowerEdge M1000e RACADM Command Line Reference Guide.

Enabling the CMC Network Interface

To enable/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
