Test Radius send request with wrong port

[oscardenizjensen]

Hej
We are testing BNG on ASR9903 (7.11.1). We setup a radius server and want to do a test for a user, but when I do the test radius command I see it uses a different port (1645-1646) instead of the configured ports 1812-1813. 

Do you guys know what causes this?

radius source-interface Loopback0 vrf default
radius-server vsa attribute ignore unknown
radius-server host 192.168.66.1 auth-port 1812 acct-port 1813
!
aaa group server radius RADIUS-TEST
server 192.168.66.1 auth-port 1812 acct-port 1813
!
aaa authentication subscriber default group RADIUS-TEST

in test command you need to specify port or override it, again this what we do in IOS XE

I do not think the command exists in XR. I used ? all the way through after each line but never given the option for entering/overriding the test port

Hello,

I understand you are using BNG ? What if you use 'diameter' (aaa group server diameter) ?

PS: In addition, which RADIUS server (and version) are you using ?
