29.3 DSCP-to-IEEE802.1p Priority Settings
You can configure the DSCP to IEEE802.1p mapping to allow the switch to prioritize all
traffic based on the incoming DSCP value according to the DiffServ to IEEE802.1p mapping
table.
The following table shows the default DSCP-to-IEEE802.1P mapping.
29.3.1 Configuring DSCP Settings
To change the DSCP-IEEE 802.1p mapping click the DSCP Setting link in the DiffServ
screen to display the screen as shown next.
* Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this row
first to set the common settings and then make adjustments on a port-by-port basis.
Note: Changes in this row are copied to all the ports as soon as you
make them.
Active Select this option to enable DiffServ on the port.
Apply Click Apply to save your changes to the switch’s run-time memory. The switch loses
these changes if it is turned off or loses power, so use the Save link on the top
