The columns in Figure 23 on page 65 display the following information:
Port Index
Displays the port number. The All value refers to ports 1 through 26 on
the AT-FS750/24POE switch and ports 1 through 26 on the
AT-FS750/24POE switch and ports 1 through 50 on the AT-FS750/48
switch.
Trunk
Displays the trunk number if the port is a member of a trunk.
PVID
Displays the Port VLAN identifier (PVID) of the port. For more
information about this field, see “Port VLAN Identifier” on page 49.
Queue
Displays the number of the queue where untagged packets received
on the port are stored on the egress queue. In this field, 0 is the lowest
value and 3 is the highest value.
Override
Displays whether the priority level in ingress tagged frames is being
used or not. If the parameter is set to Disable, the override is
deactivated and the port uses the priority levels contained within the
frames to determine the egress queue. If the parameter is set
to Enable, the override is activated and the tagged packets are stored
in the egress queue specified in the Queue column.
3. To change the egress queue where ingress untagged frames received
on a port will be stored on the egress port, use the pull-down menu in
the Queue column and select the desired queue. The range is 0
(lowest) to 3 (highest). The default is 0. For example, if you select 3 for
queue 3 for a port, all ingress untagged packets received on the port
are stored in egress queue 3 on the egress port. (If you perform Step 3
and override the priority level in ingress tagged packets, this also
applies to tagged packets as well.)
If the selected port is part of a port trunk, all ports in the trunk are
automatically assigned the same egress queue.
4. To configure a tagged port so that the switch ignores the priority tag in
ingress tagged frames, select Enable from the Override column for the
corresponding port.
The default for this parameter is Disable, meaning that the priority
level of tagged frames is determined by the priority level specified in
the frame itself.
5. Click Apply.
