JUNOSe 11.0.x Broadband Access Configuration Guide
The E Series RADIUS client uses the IP address in the router ID unless you explicitly
set an IP address by using the radius update-source-addr command. See "Configuring
RADIUS Authentication and Accounting Servers" on page 18.
To explicitly set the source address, perform the following tasks:
NOTE: For additional RADIUS information about topics such as restricting user access,
vty line authentication, or SSH, see the Passwords and Security chapter in JUNOSe
System Basics Configuration Guide.

RADIUS Services

RADIUS provides three distinct services:

RADIUS Attributes

JUNOSe software supports the RADIUS attributes and vendor-specific attributes (VSAs)
listed in this chapter. These attributes define specific authentication, authorization,
and accounting elements in a user's profile. The profile is stored on the RADIUS
server. RADIUS messages contain RADIUS attributes to communicate information
between an E Series Broadband Services Router and the RADIUS server.
Note these guidelines about RADIUS attribute numbers:
For a complete list of RADIUS attributes supported by JUNOSe software, see "RADIUS
IETF Attributes" on page 253.

RADIUS Platform Considerations

RADIUS is supported on all E Series routers.

RADIUS Platform Considerations
Configure the RADIUS update-source address.
Set this address on the RADIUS server if required.
Authentication Determines whether or not a user is allowed to access a specific
service or resource.
Authorization Associates connection attributes or characteristics with a specific
user.
Accounting Tracks service use by subscribers.
The number, such as [1], that appears in brackets before each attribute is the
attribute's standard number.
Any attribute number beginning with 26, such as [26-1], identifies a
vendor-specific attribute.
