Whether the FreeRADIUS supports switch 3Com 5500G-EI ?

Hi,all. I wish to dispose authorization on the switch with the dynamic isolation VID on the port on the protocol of 802.1x on RADIUS Server. Stand: the switch of 3Com 5500-EI (Software Of version of 3Com OS Of v3.02.03s56), computer from OS Windows XP (SP2), RHEL 5 update 1, freeradius-1.1.3-1.2.el5,kernel 2.6.18-53.el5 #1 SMP. Technical support of the 3Com has advised to use here this document for adjustment: http://www.3com.com/products/en_US/result.jsp?selected=2&sort=effdt&order=de... DUA1725-0BAA02.pdf , page 415 The authorization to FreeRadius is passed at the given moment, but to port is not allotted necessary VID. FreeRADIUS does not support 3Com switches ?
