Table 42
Radius Configuration fields
Field Description
Vendor Id for Group
Attributes
Specifies the vendor-specific attribute used by the RADIUS
server to send group names to the Nortel SNAS 4050. The
default Vendor-Id is 1872 (Alteon).
To use a standard RADIUS attribute rather than the
vendor-specific one, set the vendor ID to 0 (see also
vendor type).
Note: If the Authentication Protocol is CHAPv2, the
Vendor-Id must be set to 311 (Microsoft).
Vendor Type for Group
Attributes
Specifies the Vendor-Type value used in combination with
the Vendor-Id to identify the groups to which the user
belongs. The group names to which the vendor-specific
attribute points must match names you define on the Nortel
SNAS 4050. The default is 1.
If you set the vendor ID to 0 in order to use a standard
RADIUS attribute (see vendor ID), set the vendor type to a
standard attribute type as defined in RFC 2865. For
example, to use the standard attribute Class, set the
vendor ID to 0 and the vendor type to 25.
Vendor Id for Domain ID
Attributes
Specifies the vendor-specific attribute used by the RADIUS
server to send domain names to the Nortel SNAS 4050.
The default Vendor-Id is 1872 (Alteon).
Note: If the Authentication Protocol is CHAPv2, consider
setting the Vendor-Id for the domain to 10
(MS-CHAP-Domain).
Vendor Type for Domain ID
Attributes
Specifies the Vendor-Type value used in combination with
the Vendor-Id to identify the domain. The default is 2.
Radius Server Timeout Sets the timeout interval for a connection request to a
RADIUS server. At the end of the timeout period, if no
connection has been established, authentication will fail.
Acceptable values are an integer that indicates the time
interval followed by a letter to specify the measurement
unit. The options for measurement units are:
• s — seconds
• m — minutes
• h — hours
If you do not specify a measurement unit, seconds is
assumed. The range is 1–10000 seconds. The default is
10 seconds.
