802.1x on switch 3Com Officeconnect managed gigabit switch not working with NPS Windows Server 2012

[Bahri]

Hi,

i have a problem with switch 3com officeconnect gigabit switch 8 port when i want to use 802.1x feature.

i have configured windows server 2012 as a radius server.

and then i configured 3com switch with 

1. enabled 802.1x and set radius server and secret key

2. on interface i set auto for enable 802.1x authentication

but, when i tried to authenticate. it always failed, when i check on event viewer server, 

my server didn't received any request from radius client ( switch 3 com)

and then i tried this server with another switch from different vendor.

it's working.

so i want to ask whether 3com officeconnect can support 802.1x?

if it support, what configuration is required for activate 802.1x either on switch and server.

Thank you
