Viewing and Modifying CMC Network LAN Settings
The LAN settings, such as community string and SMTP server IP address, aect both the CMC and the external settings of the chassis.
If you have two CMCs (active and standby) on the chassis that 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 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 Conguration Administrator privilege to set up CMC network settings.

RACADM
To view IPv4 settings, use the objects from the cfgCurrentLanNetworking group with the following getniccfg and getconfig
subcommands.
To view IPv6 settings, use the objects from the cfgIpv6LanNetworking group 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 VRTX RACADM
Command Line Reference Guide.
