Vyos ppp interfaces does not contains username

General questions
1

vyos creates ppp interfaces of pppoe server without usernames which causes issue regarding logs. It would be beteer if ppp interface should also contain username like in mikrotik

2

This can be done on the RADIUS server. I have this in my freeradius 3.0 sites-available/default:

post-auth {
update reply {
NAS-Port-Id = “ppp-%{Stripped-User-Name}”
}
…
}

Freeradius is quite complex to configure, perhaps there is something different in my local setup here. Good you got it working.

How long is it? Stripped-User-Name (removes the part after @) if that’s unique and short enough, may need some tweaking I don’t remember (configured RADIUS long time ago and not touched since then). Again freeradius is complex, not easy to configure. But once set up properly, it is stable and just works.

this will work ?

post-auth {
if (NAS-Port-Id) {
rewrite {
# Check if NAS-Port-Id is longer than 15 characters
if (strlen(“%{NAS-Port-Id}”) > 15) {
# Rename NAS-Port-Id to the first 15 characters
update request {
NAS-Port-Id := substr(“%{NAS-Port-Id}”, 0, 15)
}
}
}
}
}
