QoS with new config structure fails to commit simple match rules

[May]

Continuing the discussion from Qos policy fails to commit any match rule after changing config structure:

While testing I’ve tried to setup simplest config I can imagine to be successfully committed.
Here it is:

vyos@host# show qos
 interface eth3 {
     egress TEST
 }
 policy {
     shaper TEST {
         bandwidth 61mbit
         class 100 {
             bandwidth 12mbit
         }
         default {
             bandwidth 20mbit
         }
     }
 }

Then if I try to add simple match like:

set qos policy shaper TEST class 100 match TESTMATCH ip protocol udp

so we have:

vyos@host# show qos policy shaper TEST 
 bandwidth 61mbit
 class 100 {
     bandwidth 12mbit
+    match TESTMATCH {
+        ip {
+            protocol udp
+        }
+    }
 }
 default {
     bandwidth 20mbit
 }

and commit returns:

vyos@host# commit
[ qos ]

[edit]

Am I doing something wrong or it is a bug?

[May]

but if I add other match like:

vyos@host# set qos policy shaper TEST class 100 match TESTMATCH mark 1024 
[edit]
vyos@host# compare 
[qos policy shaper TEST class 100]
+ match TESTMATCH {
+     mark "1024"
+ }

[edit]
vyos@host# show qos policy shaper TEST 
 bandwidth 61mbit
 class 100 {
     bandwidth 12mbit
+    match TESTMATCH {
+        mark 1024
+    }
 }
 default {
     bandwidth 20mbit
 }

commit goes well.
