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 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
NOTE:
If you disable CMC network interface, the disable operation performs the following actions:
● Disables the network interface access to out-of-band chassis management, including iDRAC and IOM management.
● Prevents the down link status detection.
● To disable only CMC network access, disable both CMC IPv4 and CMC IPv6.
NOTE: The CMC NIC is enabled by default.
