Enable 802.1p/DSCP-Based Quality of
Service
Note: 802.1p-based QoS is available on all models. DSCP-based QoS is available on
models GS105Ev2, GS105PEv2, GS108Ev3, GS108PEv3, GS305E, and GS308E only.
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.
If you do not know the IP address of the switch, see Access the Switch Using a Web
Browser on page 16.
The login window opens.
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.
