systems. As a RADIUS server, IAS performs centralized connection 
authentication, authorization, and accounting for network access servers 
(desktop switches and wireless access points acting as radius clients), see 
Figure 2. 
Remote Access Policy
For 3Com Network Access Manager to authenticate users and computers 
accessing the network, an IAS Remote Access Policy must be created. 
Appendix A provides step by step instructions on how to create a Remote 
Access Policy.
In a mixed-vendor network where only 3Com switches are to be 
authenticated through 3Com Network Access Manager, the Remote 
Access Policy needs to be adjusted to only match 3Com devices.

Rules
3Com Network Access Manager provides its functionality through a set 
of rules implemented in Active Directory. Each rule comprises a priority, a 
Network Access setting (allow/deny), an optional authorization response 
(VLAN and QoS), and an optional EFW policy name. 
Users, groups and computers (through the MAC address of the PC) are 
associated with rules. When multiple rules are associated with a user, 
group or computer then the rule with the highest priority takes 
precedence.
