Groups of Commands Requiring Confirmation
In 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
<name of the group> 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 not
in the local management session via the RS-232 interface but via Telnet the management session
breaks and the unit waits for the second connection within 5 minutes (for the LINE group
– 30
minutes). If the LINE group was changed remotely (using the CONNECT command), the unit waits
for the second connection within 30 minutes. If within this time the operator did not enter the modem
menu, the changed parameters are read from the startup configuration of the unit. Therefore, it is
possible to restore the configurations of the unit.
A “successful” configuration can become the
startup configuration by using the CONFIRM command.
