PPPoE Agent Remote-ID and DSL Line 
Characteristics Enhancement

12.2(31)SB2 The PPPoE Agent Remote-ID and DSL Line Characteristics 

Enhancement feature provides a method by which the digital 
subscriber line access multiplexer (DSLAM) sends the DSL 
Remote-ID tag in the discovery phase as an identifier for the 
authentication, authorization, and accounting (AAA) access 
request on an Ethernet interface, thereby simulating ATM-based 
broadband access, but using cost-effective Ethernet instead. This 
Remote-ID tag is useful for troubleshooting, authentication, and 
accounting.
