Reply items are RADIUS attributes that are used to configure the Terminal Server or NAS when a user is successfully authenticated.

In order to determine what RADIUS attributes you need to configure your NAS, you will need to consult your NAS vendor's documentation. Some RADIUS attributes are common to all NASs, and can be used with any NAS, while some are specific to a particular vendor or model of NAS. All reply items that you use must be defined in your dictionary.

If the user is granted access, all the reply items will be returned in the Access-Accept message to the NAS. This is usually used to configure the NAS in the correct way for that user. Since different brands and models of NAS implement different subsets of the radius specification, it is not possible here to describe all the things you can configure in your NAS with reply items. Refer to your NAS vendor's documentation. Here is a typical example to configure a NAS for a dial-up PPP session:

Framed-Protocol = PPP,
Framed-IP-Netmask = 255.255.255.255,
Framed-Routing = None,
Framed-MTU = 1500,
Framed-Compression = Van-Jacobson-TCP-IP

Some reply items are given special treatment:
