▀ RADIUS Change of Authorization and Disconnect Message

RADIUS Change of Authorization and Disconnect Message
This section describes how the system implements CoA and DM RADIUS messages and how to configure the system to
use and respond to CoA and DM messages.

CoA Overview

The system supports CoA messages from the AAA server to change data filters associated with a subscriber session.
The CoA request message from the AAA server must contain attributes to identify NAS and the subscriber session and a
data filter ID for the data filter to apply to the subscriber session. The filter-id attribute (attribute ID 11) contains the
name of an Access Control List (ACL). For detailed information on configuring ACLs, refer to the IP Access Control
Lists chapter in the System Administration Guide.
If the system successfully executes a CoA request, a CoA-ACK message is sent back to the RADIUS server and the data
filter is applied to the subscriber session. Otherwise, a CoA-NAK message is sent with an error-cause attribute without
making any changes to the subscriber session.
Important:
requests can be sent through AAA server requesting for one attribute change per request.

DM Overview

The DM message is used to disconnect subscriber sessions in the system from a RADIUS server. The DM request
message should contain necessary attributes to identify the subscriber session. If the system successfully disconnects the
subscriber session, a DM-ACK message is sent back to the RADIUS server, otherwise, a DM-NAK message is sent
with proper error reasons.
