Port Priority
Set Port Priority
QoS > Port Priority
The Port Priority values are assigned to an untagged frame at ingress for internal
processing in the switch. This procedure explains how to change the default mappings of
port priorities to the User Priority. This is set at the switch level. You cannot set this at
the per-port level. To change the port priority mappings, perform the following
procedure.
1. Log into your switch management page (see “Access your switch management page”
on page 5).
2. Click on QoS and click on Port Priority.
3. For each port whose priority you want to change, select a priority (0-7, Ignore) in the
User Priority column. Click Apply to save the settings.
4. At the bottom of the left hand panel, click Save.
5. Select the Config you would like to save the settings to, click Save Settings to Flash,
then click OK.
Note: This step saves all configuration changes to the NV-RAM to ensure that if the
switch is rebooted or power cycled, the configuration changes will still be applied.
DSCP
Set DSCP (Differentiated Services Code Point) Class Mapping settings
QoS > DSCP
If you choose to use the DSCP tags in your Access Control policy configuration, each
DSCP value (0-63) that is relevant to your configuration needs to be mapped to one of
the four egress queues(Low, Medium, High, or Highest). The default queue for all DSCP
values is 0.To assign the queue mappings to the DSCP values, perform the following
procedure.
1. Log into your switch management page (see “Access your switch management page”
on page 5).
2. Click on QoS and click on DSCP.
3. For each DSCP In value that is relevant to your configuration, select a queue (Low,
Medium, High, or Highest) in the Queue column. Select Enabled in the DSCP Mapping
drop-down list. Click Apply to save the settings.
4. At the bottom of the left hand panel, click Save.
