[j-nsp] Assigning IP PREC-6 for HTTP traffic of ae0.2 interface

[medrees]

Hi Expertise

       Can you help me to assign IP-PREC 6 for all HTTP traffic received
from ae0.2 aggregate sub-interface where I tried that using firewall filter
and it failed and gave me message "then dscp" not supported on ae0".

These is the applied configuration

R# show firewall family inet filter SET-PREC-6 
term PREC-6 {
    then {
        accept;
        dscp cs6;
    }
}

{master}[edit]
R# show interfaces ae0.2 
vlan-id 2;
family inet {
    filter {
        input SET-PREC-6;
    }

R# commit check 
re0: 
[edit interfaces ae0 unit 2 family inet]
  'filter'
    Referenced filter 'SET-PREC-6' can not be used as "then dscp" not
supported on ae0. 
error: configuration check-out failed
