PowerConnect 3548p multiple 802.1x auth

Hello!

We are using several PowerConnect 3548p  switches with Cisco IP Phones 7941 series and notebooks. Notebooks had been connected through  PC Port on Cisco IP Phone. And Cisco IP Phone had been connected to PowerConnect 3548p. I want to setup 802.1x authentication for both phones and notebooks.  Does PowerConnect 3548p support multiple 802.1x authentication per port? I have read  documentation, but this point doesn't  clear for me.  Please help me with answer.

Thanks!
