 Per-unit/shared/hierarchical scheduler for CoS requires VLAN tagging on SRX high-end device.

Solution

 

To fix the issue, configure the following: 

[edit interfaces ge-0/0/3]
root# show
per-unit-scheduler;
vlan-tagging;
unit 10 {
    vlan-id 10;
    family inet {
        address 78.111.162.26/30;
    }
}
Note:Thevdevice that is connected to this interface does recognize this VLAN tagging.
