Configuring Dynamic Interfaces Using Bulk
Configuration
Overview
Copyright © 2010, Juniper Networks, Inc.
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 619
Platform Considerations on page 622
References on page 624
Configuring ATM 1483 Dynamic Subinterfaces on page 624
Configuring VLAN Dynamic Subinterfaces on page 653
Monitoring Dynamic Interfaces and Profiles on page 682
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 511 in "Configuring Dynamic Interfaces" on page 511.
