The Queue Management Type field displays the queue depth management technique
that is used for queues on the interface. By default, this method is Taildrop, irrespective
of your selection from the Scheduler Type menu.
Map 802.1p Priorities to Queues
You can view or change which internal traffic classes are mapped to the 802.1p priority class
values in Ethernet frames that the device receives. The priority-to-traffic class mappings can
be applied globally or per interface. The mapping allows the switch to group various traffic
types (for example, data or voice) based on their latency requirements and give preference to
time-sensitive traffic.
 To map 802.1p priorities to queues:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is of
f-network using an Ethernet cable.
2. Launch a web browser.
3. In the address field of your web browser
, enter the IP address of the switch.
If you do not know the IP address of the switch, see Change the Default IP Address of the
Switch on page 11.
Your web browser might display a security message, which you can ignore. For more
information, see Access the Local Browser Interface on page 19.
The login window opens.
4. Enter the switch’
s password in the Password field.
The default password is password.
The System Information page displays.
5. Select QoS > CoS >
Advanced > 802.1p to Queue Mapping.
6. In the 802.1p to Queue Mapping table, map each of the eight 802.1p priorities to a queue
(internal traffic class) from 0 to 7.
The 802.1p Priority row contains traffic class selectors for each of the eight 802.1p
priorities to be mapped.
The priority goes from low (0) to high (7). For example, traffic with
a priority of 0 is for most data traffic and is sent using best effort. Traffic with a higher
priority, such as 7, might be time-sensitive traffic, such as voice or video.
The values in the menu under each priority represent the traffic class. The traffic class is
the hardware queue for a port. Higher traf
fic class values indicate a higher queue
