How PortMaster Address Assignment Works
The order of priority for address assignment is as follows for a user dialing in and
expecting to receive an address from an assigned pool:
1. If a named IP pool is configured in the pool table and the RADIUS user profile has
the IP-Pool-Name attribute configured for the user, the PortMaster assigns an
address from the named IP pool.
2. If the IP-Pool-Name attribute is not configured in the RADIUS user profile and an
address range is configured for the Quad T1 or Tri E1 board that the user comes in
on, the PortMaster assigns the user an address from the address range configured for
the Quad T1 or Tri E1 board.
3. If the IP-Pool-Name attribute is not configured in the RADUS user profile and the
Quad T1 or Tri E1 board’s assigned range is set to 0.0.0.0, and a default IP pool is
configured in the pool table, the PortMaster assigns the user an address from the
address range specified for the default IP pool.
Displaying Named IP Pool Information
Use the show table ippool command to display IP pool configuration information. For
example, to display the configuration for an entire IP pool and to view all entries, enter
the following command:
Command> show table ippool
Name: livermore Default Gateway: 10.23.45.56
Address/netmask Gateway
------------------ -----------------
192.168.1.0/29 0.0.0.0
192.168.2.253/30 0.0.0.0
192.168.3.50/25 0.0.0.0
10.4.5.0/24 192.168.222.3
Refer to your RADIUS documentation for information about modifying a RADIUS
dictionary.
Creating Named IP Pools
To add a named IP pool to the pool table, use the following command:
Command> add ippool Name
An IP pool name can contain up to 31 characters. There is no limit to the number of IP
pool entries you can configure. When you add a named IP pool to the pool table on the
PortMaster, you must also add the IP-Pool-Name attribute to the RADIUS user profile.
