Feature History for RADIUS Attribute Screening
Restrictions for RADIUS Attribute Screening
The following restrictions apply to the RADIUS Attribute Screening feature:
• Network Access Server (NAS) Requirement
To enable the RADIUS Attribute Screening feature, you should configure the Cisco 10000 router,
acting as the NAS, for authorization with RADIUS groups.
• Accept or Reject Lists Limitations
The two filters used to configure accept or reject lists are mutually exclusive; therefore, you can
configure only one accept list or one reject list for each purpose and for each server group.
• Vendor-Specific Attributes
The RADIUS Attribute Screening feature does not support vendor-specific attribute (VSA)
screening. However, you can specify attribute 26 (Vendor-Specific) in an accept or reject list, which
will accept or reject all VSAs.
• Required Attributes
Required attributes in a reject list are allowed to pass through. Do not reject the following required
attributes:
–
Authorization—6 (Service-Type) and 7 (Framed-Protocol)
–
Accounting—4 (NAS-IP-Address), 40 (Acct-Status-Type), 41 (Acct-Delay-Time), and44
(Acct-Session-ID)
Note When you configure a reject list with required attributes, an error message does not appear because the
list does not specify a purpose (authorization or accounting). The server determines if an attribute is
required when the attribute’s purpose is known.
Prerequisites for RADIUS Attribute Screening
Before you configure a RADIUS accept or reject list, enable AAA using the aaa new-model command
in global configuration mode. For more information, see the Cisco IOS Command Summary, Volume
