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.
