Hi, i have 3 Vyos Installed, version 1.2 1.4 and 1.3rc

In the 3 i have testing pppoe server, everything work ok with radius but the COA request is not working

Hello @AlvinTLC , did you configure CoA on VyOS side?

set service pppoe-server authentication radius dynamic-author server 172.16.101.100
set service pppoe-server authentication radius dynamic-author key SomeKey
set service pppoe-server authentication radius dynamic-author port 3799

Hi look my config

pppoe-server {
access-concentrator ACN
authentication {
mode radius
radius {
dynamic-author {
key ****************
port 3799
server 172.16.0.64
}
nas-identifier 172.16.101.100
nas-ip-address 172.16.101.100
rate-limit {
attribute Velocidad
vendor /usr/share/accel-ppp/radius
}
server 172.16.0.64 {
key ****************
}
source-address 172.16.101.100
}
}
gateway-address 10.100.100.1
interface eth4 {
}
interface eth7.100 {
}
}
ssh {

Why server is 172.16.0.64. Do you have configured this IP on some interface on this router?

I see you example and i put

and now works, thanks.

What you can tell me about this issue

(18) perl: ERROR: Failed to create pair - Invalid vendor name in attribute name “OUTBYTE”
(18) perl: ERROR: &request:OUTBYTE = $RAD_REQUEST{‘OUTBYTE’} → ‘0’
(18) perl: ERROR: Failed to create pair - Invalid vendor name in attribute name “INBYTE2”
(18) perl: ERROR: &request:INBYTE2 = $RAD_REQUEST{‘INBYTE2’} → ‘0’

It looks like your radius server does not know some Vendor/Attribute

Ok i will try to fix it. thanks Dmitry.
