Cisco Systems Servers Manuale Utente

To use IP pools, the AAA client must have network authorization (

authorization network

) and accounting (

aaa accounting

) enabled.

To use the IP Pools feature, you must set up your AAA client to perform 
authentication and accounting using the same protocol—either TACACS+ or 
RADIUS.

For information on assigning a group or user to an IP pool, see the

Cisco Secure ACS provides automated detection of overlapping pools.

 To use overlapping pools, you must be using RADIUS with virtual private 
networking, and you cannot be using Dynamic Host Configuration Protocol 
(DHCP).

You can determine whether overlapping IP pools are currently allowed by 
checking which button appears below the AAA Server IP Pools table:

Allow Overlapping Pool Address Ranges—Indicates that overlapping IP 
pool address ranges are currently not allowed. Clicking the button allows IP 
address ranges to overlap between pools.

Force Unique Pool Address Range—Indicates that overlapping IP pool 
address ranges are currently allowed. Clicking the button prevents IP address 
ranges from overlapping between pools.
