для Cisco Cisco IOS Software Release 12.2(27)SBC

When the vendor-tag remote-id service command is configured in broadband access (BBA) group 
configuration mode, the BRAS processes the received PPPoE vendor-specific tag in the PADR frame and 
extracts the Remote-ID tag, which is sent to the remote AAA server as a VSA in all AAA access and 
accounting requests. When the radius-server attribute 31 remote-id global configuration command is 
also configured on the BRAS, the Remote-ID value is inserted into attribute 31.

Outgoing PAD Offer (PADO) and PAD Session-Confirmation (PADS) packets from the BRAS have the 
DSLAM-inserted Remote-ID tag. The DSLAM should strip the tag out of PADO and PADS frames. If 
the DSLAM cannot strip off the tag, the BRAS must remove the tag before sending the frames out. This 
is accomplished using the vendor-tag strip BBA group configuration mode command. If this command 
is configured under the BBA group, the BRAS strips the incoming Remote-ID tag (and any other vendor 
tag) off of the outgoing PADO and PADS frames. This action complies with 

.

The shift toward Ethernet-based DSLAMs offers the following benefits:

Ability to use simpler and lower-cost provisioning options for DSL subscribers over an 
Ethernet-based backhaul network rather than on an ATM-based network.

Ability to use higher bandwidth connectivity options available from Ethernet that are not possible 
on ATM.

Ability to upgrade to next-generation DSLAMs with quality of service (QoS), and support for higher 
bandwidth, asymmetric dual latency modems such as the ADSL2.

Ability to inject high-bandwidth content such as video in an Ethernet network.

This section contains the following procedures:

This task describes how to configure the PPPoE Agent Remote-ID and DSL Line Characteristics 
Enhancement feature. When this feature is configured, BRAS will process the incoming PADR frames 
and send the Remote-ID field of the incoming tag to the RADIUS server as a VSA.

For DSL-Sync-Rate tags, you must enter the vendor-tag dsl-sync-rate service command under a BBA 
group. When this command is entered, the BRAS will process incoming PADR frames and send the 
DSL-Sync-Rate tags to the RADIUS server as VSAs.
