When committing pppoe-server ... "all down to earth"

Hi,
I have this kind of situation

[edit service pppoe-server]
vyos@VYOS# show interface | commands
set interface eth5.179 vlan-range ‘3000-4000’
set interface eth5.201 vlan-range ‘3000-4000’
set interface eth5.203 vlan-range ‘3000-4000’
set interface eth5.205 vlan-range ‘3000-4000’
set interface eth5.206 vlan-range ‘3000-4000’
set interface eth5.755 vlan-range ‘3000-4000’
set interface eth5.774 vlan-range ‘3000-4000’
set interface eth5.935 vlan-range ‘3000-4000’
set interface eth5.1061 vlan-range ‘3000-4000’
set interface eth5.1495 vlan-range ‘3000-4000’
set interface eth5.1517 vlan-range ‘3000-4000’
set interface eth5.1732 vlan-range ‘3000-4000’
set interface eth5.2024 vlan-range ‘3000-4000’
set interface eth5.2268 vlan-range ‘3000-4000’
set interface eth5.4067 vlan-range ‘3000-4000’
set interface eth5.4076 vlan-range ‘3000-4000’
set interface eth5.4077 vlan-range ‘3000-4000’

and tons of customers up and running …

But … if I had to add a new svlan+cvlan to the main interface, that’s if I do for example

set interface eth5.4087 vlan-range ‘3000-4000’
commit

all the customers fall down … and a tons of auth- requests arrive to the radius server few seconds after !

and really, it’s not good! How could I avoid it ?
thanks

Nobody ? Really?
I know that accel-ppp permit to add/remove vlan on the fly (via accel-cmd) … but after a commit i vyos, the accel-ppp daemon seems to be restarted, so all sessions fall.

No solutions ?

This appears to be a known bug upstream. Have you seen this article?

https://support.vyos.io/en/support/solutions/articles/103000096275-pppoe-server

Looks like you’ll have to do these ops during a maintenance window as much as a PITA it’s going to be.

It seems accel-ppp cannot corectly add interfaces without restart
