and are familiar with MAC addresses and IEEE 802.1X authentication.

Typical tasks for a network administrator using 3Com Network Access 
Manager include:

■

editing security profiles for users, groups and computers to include 
VLAN, QoS profile and EFW policy information,

■

adding computer MAC addresses,

■

setting up appropriate rules to control access to the network, to 
ensure an appropriate level of security and protection for the network,

■

setting appropriate administration privileges for network operators.

Network operators are allocated some limited administration privileges by 
network administrators, the extent of the privileges being specific to the 
individual and their role. For example, one operator may be limited to 
blocking access for specific users, whereas another operator may be 
allowed to move users between arbitrary groups.

Typical tasks for a network operator include specifying:

■

if a user is allowed access to the network,

■

if a computer (defined by the MAC address) is allowed access to the 
network,

■

if allowed access, which VLAN should the user or computer connect 
to, and using which QoS configuration, 

■

if a computer should be isolated from the main network,

■

if a user should be isolated from the main network,

■

the EFW Policy for each user when they log into a PC with an EFW NIC 
installed.

Network operators using 3Com Network Access Manager, do not need to 
understand the complexities of the network or the technicalities of 
VLANs, QoS, EFW or RADIUS.
