TOPIC: question about Log - DSLAM and BRAS

question about Log - DSLAM and BRAS 10 years 8 months ago #26641


I have a doubt about communication between DSLAM and BRAS.

Maybe this question is easier and I don't know the answer.

I have a problem and I need to know which IP address some user got in some day and I need log this information, for legal issues:

DSLAM port

My question is:

As my PPPoE authentication are the same to all users, example:
user: This email address is being protected from spambots. You need JavaScript enabled to view it.
pass: internet

How I could to log IP/port DSLAM delivery to user.

Which device is easier to log, DSLAM or BRAS.

The devices which are used are:

- Alcatel DSLAM, ethernet and ATM (all models, new and old)
- BRAS (Cisco and Juniper)



ps.: sorry about my poor English.

Hey dude,

If you get any info about "How billing/logging
is done for every user if they use PPPoE ?".
Please share with me...

I m very much interested in knowing abt IP DSLAM.

If I understood correctly you are talking about the user accounting. User accounting is not done in our DSLAMs, all user accounting are done in IP edge(BRAS).
Our DSLAM inserts user identification inside the packets(VST in PPP, option82 in DHCP) using which the BRAS do the accounting even if the users use the same username & pass.
