[j-nsp] Setting IP precedence-6 for HTTP traffic in aggregate-ethenet ae0.2 interface

[medrees]

Hi Expertise

      Can anyone help me to assign IP precedence value 6 to HTTP traffic
received from ae0.2 interface where I tried that using firewall filter to
all received traffic and it gave me that ""then dscp" not supported on ae0."

The configuration is shown below

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.
