FI48GPP, SX-FI-24GPP, SX-FI-24HF, SX-FI-2XG, and SX-FI-8XG modules. Therefore, configuring
a static MAC with a priority of 0 has no effect on QoS marking.

FIGURE 2 Determining a packet trust level - SX-FI48GPP , SX-FI-24GPP, SX-FI-24HF, SX-FI-2XG,
and SX-FI-8XG modules

The following figure illustrates how FCX, and ICX series devices determine the trust level of a packet.
As shown in the flowchart, the first criteria considered is whether the packet matches on an ACL that
defines a priority. If this is not the case and the MAC address of the packet matches a static entry, the
packet is classified with the priority of the static MAC entry. If neither of these is true, the packet is next
