Configuring the nas-port-id attribute
The PPPoE server on a BAS device uses the RADIUS nas-port-id attribute to send the access line ID received from a DSLAM device to the RADIUS server. The access line ID includes the circuit-id and remote-id. The RADIUS server compares the received nas-port-id attribute with the local line ID information to verify the location of the user.
You can configure the content of the nas-port-id attribute that the PPPoE server sends to the RADIUS server.
To configure the nas-port-id attribute:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter Layer 3 Ethernet interface/subinterface, Layer 3 virtual Ethernet interface/subinterface, VLAN interface, Layer 3 aggregate interface/subinterface, VE-L3VPN interface/subinterface, or EFM interface/subinterface view. | interface interface-type interface-number | The PPPoE server is enabled on the interface. |
3. Configure the content of the nas-port-id attribute. | pppoe-server access-line-id content { all [ separator ] | circuit-id | remote-id } | By default, the nas-port-id attribute contains only the circuit-id. |
4. Configure the nas-port-id attribute to include the BAS information automatically. | pppoe-server access-line-id bas-info [ cn-163 ] | By default, the nas-port-id attribute does not include the BAS information automatically. |
5. Configure the PPPoE server to trust the access line ID in received packets. | pppoe-server access-line-id trust | By default, the PPPoE server does not trust the access line ID in received packets. |
6. Configure the format that is used to parse the circuit-id. | pppoe-server access-line-id circuit-id parse-mode { cn-telecom | tr-101 } | The default mode is TR-101. |
7. Configure the transmission format for the circuit-id. | pppoe-server access-line-id circuit-id trans-format { ascii | hex } | The default format is a string of characters. |
8. Configure the transmission format for the remote-id. | pppoe-server access-line-id remote-id trans-format { ascii | hex } | The default format is a string of characters. |
