[c-nsp] client mac address on LNS??

[Asad Ul-Islam]

Dear Friends!

 

I have a setup in which DSL users connect to a LNS via L2TP. Everything is
working fine, however on LNS I am not receiving any MAC address for the DSL
Users( Type PPPoVPDN). This is my standard crucial requirement for
generating several reports for management purposes. 

 

Can someone tell me if it is possible to get Mac-address for the VPDN
users??? I am getting mac-address for PPPoE type users which are terminated
on my BRAS.

 

Attach is the debug output for both LNS and BRAS which shows that
mac-address field is missing in LNS output.
