Using multi-device port authentication and 802.1X security on the same port
36
Configuring Dell-specific attributes on the
RADIUS server
If the RADIUS authentication process is successful, the RADIUS server sends an Access-Accept
message to the Dell PowerConnect device, authenticating the device. The Access-Accept message
can include Vendor-Specific Attributes (VSAs) that specify additional information about the device.
If you are configuring multi-device port authentication and 802.1X authentication on the same
port, then you can configure the Dell VSAs listed in Table 225 on the RADIUS server.
You add these Dell vendor-specific attributes to your RADIUS server configuration, and configure
the attributes in the individual or group profiles of the devices that will be authenticated. The Dell
Vendor-ID is 1991, with Vendor-Type 1.
If neither of these VSAs exist in a device profile on the RADIUS server, then by default the device is
subject to multi-device port authentication (if configured), then 802.1X authentication (if
configured). The RADIUS record can be used for both multi-device port authentication and 802.1X
authentication.
Configuration examples are shown in “Examples of multi-device port authentication and 802.1X
authentication configuration on the same port” on page 1302.
TABLE 225 Dell vendor-specific attributes for RADIUS
Attribute name Attribute ID Data type Description
Foundry-802_1x-enable 6 integer Specifies whether 802.1X authentication is
performed when multi-device port
authentication is successful for a device. This
attribute can be set to one of the following:
0 - Do not perform 802.1X authentication on
a device that passes multi-device port
authentication. Set the attribute to zero for
devices that do not support 802.1X
authentication.
1 - Perform 802.1X authentication when a
device passes multi-device port
authentication. Set the attribute to one for
devices that support 802.1X authentication.
Foundry-802_1x-valid 7 integer Specifies whether the RADIUS record is valid
only for multi-device port authentication, or
for both multi-device port authentication and
802.1X authentication.
This attribute can be set to one of the
following:
0 - The RADIUS record is valid only for
multi-device port authentication. Set this
attribute to zero to prevent a user from using
their MAC address as username and
password for 802.1X authentication
1 - The RADIUS record is valid for both
multi-device port authentication and 802.1X
authentication.
