5. Enter a value from 0to 7 that corresponds to the egress queue where
you want all untagged frames on the port to be stored. For example,
if you want all ingress untagged packets received on the port stored
in egress queue Q2, enter 2. The default is 0, which corresponds to Q0.
(If you perform Step 7 and override the priority level in tagged
packets, this queue will also be used to store all tagged packets.) The
values are listed in Table 11.
6. If you are configuring a tagged port and you want the switch to
ignore the priority tag in egress tagged frames, type 4 to select
Override Priority and type Y.
All tagged frames are directed to the queue specified in Step 6.
Note
The tagged information in a frame is not changed as the frame
traverses the switch. A tagged frame leaves a switch with the same
priority level that it had when it entered.
The default for this parameter is No, meaning that the priority
level of tagged frames is determined by the priority level specified
in the frame itself.
7. Type C to select Configure Port COS Priorities.
A change to a CoS setting is immediately activated on the port.
8. If desired, repeat this procedure starting with Step 3 to configure
other ports.
9. After making changes, type R until you return to the Main Menu. Then
type S to select Save Configuration Changes.
