- queue 3 nc;
- }
- interfaces {
-
- so-1/1/3 {
-
- unit 0 {
-
- rewrite-rules {
- exp exp_rew; # Apply custom rewrite table
- exp-swap-push-push default;
- }
- }
- }
- }
- rewrite-rules {
-
- exp exp_rew {
-
- forwarding-class be {
- loss-priority low code-point 000;
- loss-priority high code-point 100;
- }
-
- forwarding-class ef {
- loss-priority low code-point 001;
- loss-priority high code-point 101;
- }
