Enable 802.1p/DSCP-Based Quality of
Service
802.1p/DSCP-based priority uses a field in the data packet header that identifies the class of
data in the packet (for example, voice or video). When 802.1p/DSCP-based priority is used,
the switch reads information in the packet header to determine the priority to assign to the
packet. The switch reads both 802.1p tag information and DSCP and ToS tag information. If
an ingress packet contains an 802.1p tag and a DSCP or ToS tag, the switch gives
precedence to the 802.1p tag.
All ports on the switch check the packet header and transmit the packet with a priority
determined by the packet content.
To enable 802.1p/DSCP-based QoS:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired network connection, or connect directly to a switch that is
off-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 Access the Switch Using a Web
Browser on page 7.
The login window opens.
4. Enter the switch’s password in the password field.
The switch’s default password is password.
The Switch Information page displays.
5. Select QoS.
The Quality of Service page displays.
6. Select the 802.1p/DSCP-based radio button.
A pop-up window opens, informing you that the current QoS settings will be lost.
7. Click the YES button.
The pop-up window closes.
8. Click the Apply button.
Your settings are saved.
