Hi Everyone,
I have a topology like this :
My DSW is 2960-XR series
My ASW is 2960-S series
Instead of configure authentication on ASW. I try to configure on DSW and connect ASWs to DSW. So i only have to config on one Sw to perform authenticate for the entire user on my network. But there is a problem, IP-phone which use MAB work fine no matter i connect it to ASW or DSW. But Laptop/PC which use DOT1X only authentication success when i connect it to DSW. Laptop/PC authentication failed when i connect to ASW even with same credentical. So i guess there are some configure i need to add on ASW right ?
Please help,
Many Thanks,
Quang
