Configuring Access 
Management
The access management function is designed to control user accesses on access 
switches. It allows you to control the access of hosts to external networks.
The idea is to bind a range of IP addresses to a port by configuring an access 
management IP address pool on the port.
If an access management IP address pool is available on a port, a host 
connected to the port can access external networks only when its IP address is 
contained in the address pool.
If no access management IP address pool is available on a port, a host 
connected to the port can access external networks so long as its IP address is 
not in the access management IP address pools of any other switch port.
