Configure Agent Circuit Identifier and IFL Sets in Juniper BNG CUPS

This document presents sample configurations that you can use to help you set up Agent Circuit Identifier and IFL Sets in your Juniper BNG CUPS environment.

Configure Agent Circuit Identifier and IFL Sets

Note:

ACI virtual VLAN sets (ACI sets) are IFL sets of client IFLs, they are not VLAN IFLs.

All service related configurations of ACI sets must be defined in the client's IFL dynamic profile. Service configurations in the ACI dynamic profile are not supported.

For examples of service configurations, see the following:

Example: Configure Class of Service
Example: Configure Dynamic Service VLAN Profile
Example: Configure Dynamic ACI Virtual VLAN Profile
Example: Targeted Distribution Configuration for IFL for DHCP
Example: Targeted Distribution Configuration for IFL for PPPoE

Configure Aggregated Ethernet Targeted Distribution

Targeted distribution configuration for IFL and IFL set is supported only when configured in a client dynamic profile. Targeted distribution is not supported for IFL and IFL set in a VLAN dynamic profile.
