Attempting to configure the nas-port-id-format option for a dot1x access profile due to the need to have the RADIUS server differentiate between different port groups. However, even after configuring the following:

set access profile DOT1X radius options nas-port-id-format interface-description interface-text-description

the switch is still only sending the interface-description (default) in the NAS-Port-Id attribute to the RADIUS server:

(39) NAS-Port-Id = "ge-0/0/8.0"

The custom order variety of the command produces the same (ineffective) result:

set access profile DOT1X radius options nas-port-id-format order [ interface-description interface-text-description ]

This option is not available as of now, for the EX2300-C devices, and this is only configurable for some MX devices. This can be confirmed the same on the following link, on on the following link: https://apps.juniper.net/feature-explorer/feature/1478?fn=NAS-Port-ID%20format%20enhancement
