DT Etherlink IV User Manual- 46 -confirm this configuration. In this case, changes in all groups are copied from the runningconfiguration into the startup configuration.Figure 4.3 Operations of configuration parameters that should be confirmed4.4 Groups of Commands Requiring ConfirmationIn Etherlink_IV devices the following four groups of parameters require a confirmation: LINE, NET,VLAN and SNMP. Changing configurations of each group use some special commands. The APPLY command is used to apply changes in configurations performed in a group.After this, the unit applies changes in configurations. If groups LINE, NET, VLAN were changed notin the local management session via the RS-232 interface but via Telnet the management sessionbreaks and the unit waits for the second connection within 5 minutes (for the LINE group – 30minutes). If the LINE group was changed remotely (using the CONNECT command), the unit waitsfor the second connection within 30 minutes. If within this time the operator did not enter the modemmenu, the changed parameters are read from the startup configuration of the unit. Therefore, it ispossible to restore the configurations of the unit. A “successful” configuration can become thestartup configuration by using the CONFIRM command.4.5 Command SyntaxThe following rules are used to describe commands: parameters in angular brackets < > are obligatory parameters in direct brackets [ ] are not obligatory the symbol ( / ) between parameters requires to enter one of the listed parameters in real commands brackets and vertical line are not entered, they are used for description after the command is typed, press ChangingvaluesStartup configuration Backup configurationRunning configurationNew configurationAppling of changes(command APPLY)Confirming of changes(command CONFIRM)LoadingLoadingSaving of backup copy(command BACKUP)Configuration changingRestoring from backup copy(command RESTORE)
