Configuring the RADIUS DAE server feature
Dynamic Authorization Extensions (DAE) to RADIUS, defined in RFC 5176, can log off online users
or change their authorization information. DAE uses the client/server model.
In a RADIUS network, the RADIUS server typically acts as the DAE client and the NAS acts as the
DAE server.
When the RADIUS DAE server feature is enabled, the NAS performs the following operations:
1.
Listens to the default or specified UDP port to receive DAE requests.
2.
Logs off online users who match the criteria in the requests, or changes their authorization
information.
3.
Sends DAE responses to the DAE client.
DAE defines the following types of packets:
•
Disconnect Messages (DMs)
—The DAE client sends DM requests to the DAE server to log off
specific online users.
•
Change of Authorization Messages (CoA Messages)
—The DAE client sends CoA requests
to the DAE server to change the authorization information of specific online users.
