The Ingress VLAN Translation table allows for up to 15 entries for each port. One or multiple fields can be selected from the packet header for lookup in the Ingress VLAN Translation table. The S-VLAN or C-VLAN or both configured in the first matched entry are assigned to the packet.

Enables or disables PCP propagation.

• If the port type is Edge, the customer PCP is copied from the service PCP.
• If the port type is Network, the service PCP is copied from the customer PCP.

Below is a table of traffic that triggers a rule that has a certain VLAN format set; note that traffic that is tagged with VLAN ID 0 is a special case that is also taken into account.

Danger If VLAN-format is set to any, then customer-vid``/``service-vid set to 0 will trigger the switch rule with VLAN 0 traffic. In this case, the switch rule will be looking for untagged traffic or traffic with a VLAN 0 tag, and only untagged-or-tagged will filter out VLAN 0 traffic.
