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/ToS tag information. If an ingress packet contains both an 802.1p tag and a DSCP/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.
The login page displays.
4. Enter the switch password.
The default password is password. The password is case-sensitive.
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 OK button.
The pop-up window closes.
8. Click the Apply button.
Your settings are saved.
Configure Port-Based Quality of Service
You can assign a priority to all data passing through a particular port. Data with a higher priority is transmitted
faster. If packets arrive at several ports at the same time, the ports configured as higher priority transmit
their packets first.You must determine which ports will carry delay-sensitive data.
