Queues for Radius Bases PPPoE Client

I recently configured a Vyos Based PPPoe NAS server.
I am facing a issue that all local users are getting connect on their set limits but Radius bases PPPoE users are getting connected without limits.

pppoe-server {
access-concentrator exceednet
authentication {
local-users {
username ritu {
password ****************
}
username test {
password ****************
rate-limit {
download 20000
upload 20000
}
}
}
mode radius
radius {
dynamic-author {
key ****************
port 3799
server 54.254.110.117
}
nas-identifier 1
nas-ip-address 103.x.x.x/30
preallocate-vif
rate-limit {
enable
}
server 54.254.110.117 {
acct-port 1813
key ****************
port 1812
}

already did the same but no luck

What version of VyOS are you using ?

Show command output:

show pppoe-server sessions

issue resolved by applying rate-limite, vendore and multiplier ,
thanks…
