For example, the following AV pair causes Cisco ’ s “ multiple named IP address pools ” feature to be activated
during IP authorization (during PPP
’
s Internet Protocol Control Protocol (IPCP) address assignment):
cisco-avpair=
”
ip:addr-pool=first
“
If you insert an
“
*
”
, the AV pair
“
ip:addr-pool=first
”
becomes optional. Note that any AV pair can be made
optional:
cisco-avpair=
”
ip:addr-pool*first
“
The following example shows how to cause a user logging in from a network access server to have immediate
access to EXEC commands:
cisco-avpair=
”
shell:priv-lvl=15
“
Other vendors have their own unique vendor-IDs, options, and associated VSAs. For more information about
vendor-IDs and VSAs, see RFC 2138,
“
Remote Authentication Dial-In User Service (RADIUS).
”
Attribute 26 contains the following three elements:
• Type
• Length
• String (also known as data)
• Vendor-Id
• Vendor-Type
• Vendor-Length
• Vendor-Data
The figure below shows the packet format for a VSA encapsulated
“
behind
”
attribute 26.

It is up to the vendor to specify the format of their VSA. The Attribute-Specific field (also known as
Vendor-Data) is dependent on the vendor's definition of that attribute.
Note
The table below describes significant fields listed in the Vendor-Specific RADIUS IETF Attributes table
(second table below), which lists supported vendor-specific RADIUS attributes (IETF attribute 26).
