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.
