Hierarchy Level


Specify the information that is excluded from the interface description that the device passes to RADIUS for inclusion in the RADIUS attributes such as NAS-Port-ID (87) or Calling-Station-ID (31).

The default format for nonchannelized interfaces is as follows:


For example, consider physical interface ge-1/2/0, with a subinterface of 100 and SVLAN identifier of 100. The interface description used in the NAS-Port-ID is ge-1/2/0.100:100. If you exclude the subinterface, the description becomes ge-1/2/0:100.

The default format for channelized interfaces is as follows:


The channel information (logical port number) is determined by this formula:

Logical port number = 100 + (actual-port-number x 20) + channel-number.

For example, consider a channelized interface 3 on port 2 where the:

  • Physical interface is xe-0/1/2:3.

  • Subinterface is 4.

  • SVLAN is 5.

  • VLAN is 6.

Using the formula, the logical port number = 100 + (2 x 20) + 3 = 143. Consequently, the default interface description is xe-0/1/143.4-5.6. If you exclude the channel information, the description becomes xe-0/1/2.4-5.6.
