Manual Configuration of the NAS-Port-Type RADIUS Attribute

 

Subscriber management uses the NAS-Port-Type (RADIUS attribute 61) to identify the type of physical port that is used to authenticate subscribers. By default, subscriber management uses a NAS-Port-Type of ethernet.

You can optionally configure access profiles to provide the value for the NAS-Port-Type attribute, which enables you to explicitly specify the NAS port type that is used for a given connection. For example, you might configure an access profile that specifies that a NAS port type of wireless is used for all Ethernet connections that are managed by that access profile.

Note

The ethernet-port-type-virtual configuration statement takes precedence over the nas-port-type statement when you include both statements in the same access profile. When you include the ethernet-port-type-virtual statement, subscriber management uses the RADIUS attribute value of 5, which specifies a NAS port type of virtual.

Table 1 shows the supported port type values for RADIUS attribute 61 (NAS-Port-Type) that you can include in an access profile.
