Hi,

I need to mark the 802.1p field to 2 for every packet from my WAN interface to communicate through a link.

My configuration didn't work because the Mikrotik router didn't mark ARP packets. All other packets are well-marked.
My configuration is the following:

/interface vlan add interface=ether1 name=vlan2900 vlan-id=2900
/ip address add address=1.2.3.1/30 comment="WAN" interface=vlan2900 network=1.2.3.0
/ip firewall mangle
add action=set-priority chain=output new-priority=2 out-interface=vlan2900
add action=set-priority chain=forward new-priority=2 out-interface=vlan2900
/ip route add distance=1 gateway=1.2.3.2

Do you know how to mark ARP packets ?

Hope to receive feedback from you soon.

Thanks !
