Chapter 18
Configuring Dynamic Interfaces Using
Bulk Configuration

Overview

This chapter explains dynamic interfaces and describes the procedures for configuring
them on E Series routers.
This chapter contains the following sections:
Overview on page 623
Platform Considerations on page 627
References on page 628
Configuring ATM 1483 Dynamic Subinterfaces on page 628
Configuring VLAN Dynamic Subinterfaces on page 658
Monitoring Dynamic Interfaces and Profiles on page 689
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" on page 515 in "Configuring Dynamic Interfaces" on page 515.
