NAS-Port not present in RADIUS Accounting

RouterOS General
1

Hello,

my colleagues are setting up a new FreeRADIUS server and use one of our Mikrotik Routers for testing.

Now they noticed that one filed in the accounting log is missing.

NAS-Port

“NAS-Port-Type” and “NAS-Port-Id” do exist.

        Timestamp = 1552311122

How can we enable this field or why is it not shown in the logs?

The RADIUS-Client is a CCR1009.
RouterOS: 6.44

Can anybody help?

I configured a new Mikrotik (cAP ac) to test this an another System.
RouterOS: 6.44

Same result. No “NAS-Port” ist sent to the RADIUS-Server.
I even checked the package with tcpdump/Wireshark that arrived at the RADIUS server.
