Hello la communauté,
Pour information, il semblerait que Mikrotik va enfin sortir une version de RouterOS qui prend en charge le changement de la priorité VLAN (pcp / IEEE 802.1p) pour les paquets DHCP IPv4 .
Leur documentation est déjà prête :
https://help.mikrotik.com/docs/spaces/ROS/pages/24805500/DHCP#DHCP-Propertiesvlan-priority (integer:0..7; Default: 0) If the DHCP client is running on a VLAN interface (/interface/vlan), you can specify the Priority Code Point (PCP) value. PCP is a 3-bit field in the VLAN header used to mark the priority of packets within a VLAN, allowing traffic to be prioritized accordingly. This setting applies only to VLAN interfaces and affects the priority of outgoing DHCP client packets.
Voici la réponse automatisée de Mikrotik relatif à un ticket concernant le problème des paquets DHCPv4 (qui ne passe pas par le firewall et/ou les switchs rule) :
