Qos policy fails to commit any match rule after changing config structure

[May]

after QoS config moved from traffic-policy to qos policy it fails to commit any match rule.

what I’ve learned:

1. there is different meaning of % in bandwidth parameter
   was: “% Percentage of overall rate (default 100%)”
   now: “% Percentage of interface link speed”
2. if I pass any class with any parameters except match - it is ok.
3. if I add any match than commit causes Illegal “match” and Commit failed with something like:

try to add match for udp protocol

set qos policy shaper IN-SHAPER class 100 match UDP ip protocol udp
compare shows:
[qos policy shaper IN-SHAPER class 100]

+ match UDP {
+     ip {
+         protocol "udp"
+     }
+ }

[[qos]] failed
Commit failed

so here are two questions:

1. what am I doing wrong and how can I add match for class in new config structure?
2. is there any way to use bandwidth of class in % from parent’s queue bandwidth parameter?
