Overview

Before you begin configuring dynamic interfaces in bulk, review the concepts described in this section.

Like upper-layer dynamic interfaces, bulk-configured dynamic interfaces are created automatically and transparently through the receipt of data over a lower-layer link, such as an ATM virtual circuit (VC) or a virtual LAN (VLAN) using autodetection. The layers of a dynamic interface are created based on the packets received on the link and can be configured through any one of the following:

RADIUS authentication (through PPP or ATM 1483)
Profiles
A combination of RADIUS authentication and profiles

You create and configure each layer of a static interface manually through an existing configuration mechanism such as the command-line interface (CLI) or Simple Network Management Protocol (SNMP).

For more information about dynamic interfaces, autodetection, and RADIUS, see Overview in Configuring Dynamic Interfaces.
