Please reference the 'Configuring the CSN' section of the Installation and Configuration chapter

above for full information about each of the parameters.

When changing values for any network parameter, the console may return a list of resulting actions

that will need to be taken by each of the services and installed software modules. Because the

network configuration is central to so many services, it is not unusual for the action list to contain

service restarts and possibly a server reboot. The console will ask you to confirm you still want

to make the requested change(s) prior to proceeding after you have seen the full list of resulting

actions.

3.1.1. Updating the Internal Interface

Updating the internal interface for a CSN can be extremely disruptive as it requires a coordinated

update between the CSN and the DX Storage cluster to ensure the two are using the same

internal network interface. Updates to the internal interface should be made only when absolutely

necessary, using the following command:
