- 802.1p. IEEE 802.1p specifies eight priority tags (p0 to p7). The QoS setting
lets you map each of the eight priority levels to an internal hardware priority
queue. Models GS324T and GS324TP support four hardware queues (0 to 3)
and model GS348T supports eight hardware queues (0 to 7). The default
mode is 802.1p.
- DSCP.
The six most significant bits of the DiffServ field are called the
Dif
ferentiated Services Code Point (DSCP) bits.

Configure CoS Interface Settings for an Interface
You can configure the trust mode for one or more interfaces and apply an interface shaping
rate to all interfaces or to a specific interface.
To configure CoS settings for an interface:
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 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
Discover or Change the Switch IP
Address on page 12.
The login window opens.
4. Enter the switch’s password in the Password
field.
The default password is password.
