49.3 DSCP-to-IEEE 802.1p Priority Settings
You can configure the DSCP to IEEE 802.1p mapping to allow the Switch to prioritize all traffic based on
the incoming DSCP value according to the DiffServ to IEEE 802.1p mapping table.
The following table shows the default DSCP-to-IEEE802.1p mapping.
49.3.1 Configuring DSCP Settings
To change the DSCP-IEEE 802.1p mapping click SWITCHING > QoS > Diffserv > DSCP Setting to display the
screen as shown next.
Port This field displays the index number of a port on the Switch. In Stacking mode, the first number
represents the slot and the second the port number. * means all ports (on the same Switch).
* 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.
Changes in this row are copied to all the ports as soon as you make them.
Active Select Active 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 navigation panel to save
your changes to the non-volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
