Use New Accounting Session ID After Authentication -- Select this
checkbox if you wish to use another ID for accounting after
authentication has taken place.
Interim Update Interval -- Set the interval (in minutes) between interim
updates. The interim update is used to send information in between
normal "start/stop" packets. Interim updates are useful because they
provide a log of network traffic at a regular interval.
The default value for the interim update interval is 15 minutes. The
interim update must be between 1 - 60 minutes.
Retry Interval (1/10 sec) -- The retry interval for accounting, in tenths
of a second. The default value is 5 (or a retry interval of .5 seconds).
You can set the retry interval to any value between 3 and 30.
Maximum Retries -- The number of times the access point will retry to
connect with the server. The default value is 8, and the range for retries
is between 1 and 10.
Set Up Realms for -- When an access client sends user credentials, a
user name is often included. Within the user name are two elements:
•
Identification of the user account name
•
Identification of the user account location
For example, for the user name user1@microsoft.com, user1 is the user
account name and microsoft.com is the location of the user account. The
identification of the location of the user account is known as a realm.
With RADIUS, a realm is used to separate one name space from another.
This allows you to create a login such as user@dom1.com and another
login such as
user@dom2.com . RADIUS realms also allow Internet
Service Providers (ISPs) to segment customer logins, so authentications
go to the appropriate RADIUS server(s).
A domain is registered with the InterNIC, and used for mapping servers
and services to IP addresses, such as Web, e-mail, etc. Typically, a
RADIUS realm corresponds to a domain name (e.g., microsoft.com;
yahoo.com). However, there is no requirement to do so, and in fact ISPs
often assign realms with no top-level domain (for example, user@dom1 -
- without a .com extension).
From the dropdown list, select the accounting or authorization feature for
which to provide special handling of <RADIUS realms>. Options
