Profiles

You can use profiles to configure dynamic interfaces over ATM and VLAN interfaces. A profile is a set of characteristics that can be dynamically assigned to interfaces. By using a profile, you reduce the management of a large number of interfaces by applying a set of characteristics to multiple interfaces.

When you are configuring a large number of interfaces with the same attributes at the higher layers, you can use a profile to factor out all the common attributes of each layer into one place. This action affects one or more dynamic layers of the interface column. After you define the static lower layers, you assign a profile to the highest static layer of the interface column.

When a dynamic interface is configured, the configuration data received from the RADIUS authentication server typically overrides configuration data obtained from a profile.

The atm atm1483 auto-configure command specifies the types of dynamic upper-interface encapsulations that are accepted or detected by a dynamic ATM 1483 subinterface. For flexibility, the router provides the ability to configure an ATM 1483 subinterface with distinct profile assignments for each encapsulation type supported by the atm atm1483 auto-configure command. For more information about using this command, see atm atm1483 auto-configure.

In contrast to dynamic ATM 1483 subinterfaces, dynamic VLAN subinterfaces support recognition and creation of simultaneous IP and PPPoE upper dynamic interface types. The vlan auto-configure command identifies the encapsulation type. For flexibility, the router provides the ability to configure a VLAN subinterface with distinct profile assignments for each encapsulation type supported by the vlan auto-configure command. For more information about using this command, see vlan auto-configure.
