[c-nsp] Ethernet Authentication

[Scott Brown]

We have a WaveRider 900Mhz and Proxim WiFi network (along with Lucent DSL).
While I have yet to get it installed, our WaveRider rep told us about DHCP
Option 82. Basically, once configured right the Option 82 will pass the MAC
address of the bridge (ie: wireless CPE) to the DHCP server. I know haneWin
DHCP server can do this (what WaveRider suggests) - but I am going to try to
get it running off my Debian Linux server...

Hi,

Currently I have the same topology (with Axccelera fixed Wireless) but
instead of Routers I have Multilayer 3560 switches, after of read the
previous mails, I would know the architecture to bring to PPPoE
because I'm having a lot of problems with scalability.

Thanks in advanced...

Rgds.
