i have configured vyos router with eth0 as WAN and eth1 as LAN,with this configuration

qos {
     interface eth1 {
         egress UL-Traffic-1G
     }
     interface ifb0 {
         egress DL-Traffic-1G
     }

shaper DL-Traffic-1G {
     bandwidth 1gbit
     class 10 {
         bandwidth 100mbit
         match CUST-XXXX {
             ip {
                 destination {
                     address 123.123.123.0/30
                 }
             }
         }
     }
     default {
         bandwidth 5mbit
         priority 7
         queue-type fair-queue
     }
 }

shaper UL-Traffic-1G {
     bandwidth 1gbit
     class 10 {
         bandwidth 100mbit
         match CUST-XXXX {
             ip {
                 source {
                     address 123.123.123.0/30
                 }
             }
         }
         queue-type fq-codel
     }
     default {
         bandwidth 5mbit
         priority 7
         queue-type fair-queue
     }
 }

but what happaned is traffic limited as on default class configuration 5m not on class 10 configuration 100m, what is wrong with that configuration?
is it must to applying traffic policy to wan interface? can i applying on lan interface?
