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.
Configuring a VA pool
The PPPoE server creates a VA interface for a PPPoE session to transmit packets between PPPoE and PPP.
It removes the VA interface when the user goes offline. Creating and removing VA interfaces take time.
If a large number of users are going online or offline, the performance of PPPoE session establishment
and termination will be degraded.
You can configure a VA pool to improve the performance. A VA pool contains a group of VA interfaces.
The PPPoE server selects a VA interface from the pool for a requesting user and release the VA interface
when the user goes offline. This feature speeds up the establishment and termination of PPPoE sessions.
When a VA pool is exhausted, the system creates a VA interface for a PPPoE session, and removes it
when the user goes offline.
When you configure a VA pool, follow these guidelines:
• A VT interface can be associated with only one global VA pool, and a card can be associated with
only one regional VA pool. Users on an Ethernet interface can only use the VA pool associated with
the VT interface that is bound to the Ethernet interface. To change the capacity for a VA pool, delete
the previous configuration, and reconfigure the VA pool.
