This procedure shows how to change the parameters for
an aggregated multiservices (AMS) interface on a TDF gateway using
maintenance mode at the [edit interfaces] hierarchy level.
If an AMS interface is configured under a gateway’s session
PICs or services PICs, and you change any load-balancing options such
as membership of AMS interfaces (mams), then the AMS interface must
be in maintenance mode.
Before you change AMS parameters using maintenance mode:
To configure maintenance mode and AMS parameter change:
- Verify the current status of maintenance mode for the
AMS.

The service-mode option displays the information
details about maintenance mode as well as status.
Maintenance Mode
MM Active Phase - System is ready to accept configuration changes for all
attributes of this object and its sub-hierarchies.
MM In/Out Phase - System is ready to accept configuration changes only for
non-maintenance mode attributes of this object and
its sub-hierarchies.

ms-1/1/0 SCG1 Operational
ms-2/0/0 SCG1 Operational

- From configuration mode, show the current configuration
for the AMS interface.
user@host# show interfaces interface-name

member-interface mams-5/1/0;
member-failure-options {

many-to-one {
preferred-backup mams-5/1/0;
}
}
}
unit 1 {
family inet;
}
unit 2 {

}
- On the gateway, place the interface in maintenance mode.

- Verify that the AMS interface is in active maintenance
mode where configuration changes are accepted for this object and
all of its subhierarchies, after you commit the configuration.

Note: All subscribers serviced by the AMS interface must go
to zero. You can wait for these conditions to be met, or use the clear command for the interface (or gateway) to force these
conditions.
- Delete or change AMS member interfaces and parameters.
