5. Use the Priority list to select a value from Level 1 to Level 7 that
corresponds to the egress queue where you want all untagged
ingress packets on the port to be stored. For example, if you select
Level 4, all untagged packets received on the port are stored in egress
queue Q2 of the egress port. The default is Level 0, which corresponds
to Q0. (If you perform Step 6 and override the priority level in tagged
packets, the selected egress queue is also used to store all tagged
packets.) The default values are listed in Table 3.
6. If you are configuring a tagged port and you want the port to ignore
the priority tag in egress tagged packets, click the Override Priority
option. A check in the box indicates this feature is activated. All
tagged packets are directed to the egress queue specified in Step 6.
