(Optional) Configuring RADIUS Proxy Authentication

(Optional) Configuring RADIUS Proxy Authentication

Context

In some cases, user authentication and accounting may be performed on different devices. For example, the AC is responsible for user authentication, whereas the BRAS is responsible for user accounting. To prevent two devices from sending authentication packets to the RADIUS server at the same time, configure the BRAS that performs user accounting as a RADIUS proxy. The RADIUS proxy then records authentication information of users when forwarding RADIUS authentication packets. The BRAS with RADIUS proxy authentication configured transparently transmits RADIUS packets from a specified RADIUS client to the RADIUS server, record authorization information delivered by the RADIUS server, and transparently transmits authentication response packets. If the authentication mode configured in the user domain of the BRAS is radius-proxy, the BRAS can use the recorded authorization information to authorize users.

NOTE:
Currently, RADIUS proxy authentication takes effect for only IPoE users.

Perform the following steps on the NE40E.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run radius-client ip-address [ mask { mask-ip | mask-length } ] [ vpn-instance instance-name ] { { shared-key key | shared-key-cipher key-string-cipher } | server-group groupname | roam-domain domain-name | domain-authorization | trigger-web { authentication | accounting | none } } *

    A RADIUS client is configured, including the IP address, VPN instance, shared key, and RADIUS server group.

  3. (Optional) Run radius-client check-attribute-length loose [ correct-forwarding ]

    Loose check or correction of attribute lengths in authentication or accounting request packets is configured.

  4. (Optional) Run radius-client packet dscp dscp-value

    A DSCP value is set for RADIUS packets sent from the BRAS to the AP/AC.

  5. Run commit

    The configuration is committed.
