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.
z 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.
z A port without an access management IP address pool configured allows the hosts to access
external networks only if their IP addresses are not in the access management IP address pools of
other ports of the switch.
Note that the IP addresses in the access management IP address pool configured on a port must be in
the same network segment as the IP address of the VLAN (where the port belongs to) interface.
