Access Management Overview
Normally, client PCs in a network are connected to switches operating on the network
access layer (also referred to as access switches) through Layer 2 switches; and the
access switches provide external network accesses for the client PCs through their
upstream links. In the network shown in
Figure 1-1 , Switch A is an access switch; Switch
B is a Layer 2 switch.

The access management function aims to manage user access rights on access switches.
It enables you to manage the external network access rights of the hosts connected to
ports of an access switch.
To implement the access management function, you need to configure an IP address pool
on a port of an access switch, that is, bind a specified range of IP addresses to the port.

A port with an access management IP address pool configured only allows the hosts
with their IP addresses in the access management IP address pool to access external
networks.
