Table 133 IP Application > DiffServ LABEL Active Port * DESCRIPTION Select this option to enable DiffServ on the Switch. This field displays the index number of a port on the 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. Active Apply Cancel Changes in this row are copied to all the ports as soon as you make them. Select Active to enable Diffserv on the port. 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. Click Cancel to begin configuring this screen afresh. 34.3 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.
