ETWORK

This case study describes the tasks that need to be performed in order to 
control user access to the network using IEEE 802.1X. This method of 
authentication is based on the user, and does not perform authentication 
of the PC (or other client device) being used.

The following provides an overview of the tasks for a network 
administrator responsible for the domain on the network.

1 Ensure edge port security is set to IEEE 802.1X on edge ports in the 

domain.

Using 3Com Network Access Manager:

2 Select the Default Rule and set the Network Access to Deny, see 

“Changing Rule Properties” in Chapter 3.

3 Create an Authorized Users rule which will allow network access, see 

“Creating A New Rule”in Chapter 3. 

a Set security permissions for the rule. Grant READ and WRITE access to 

the users/groups permitted to apply the rule, grant READ access to all 
Network Administrators in the domain to ensure they can see that the 
rule exists even if they are not permitted to apply the rule.

b Set the Actions for the rule: select the rule priority, and set Network 

Access to Allow, if appropriate select the VLAN, QoS profile and EFW 
policy for the rule.

4 Associate the Authorized Users rule with users and groups already listed 

in Active Directory

5 Ensure the network operators or those individuals responsible for 

applying the Authorized Users rule have the Network Operator 
component of 3Com Network Access Manager installed on their PC.
