27.4 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.
27.4.1 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.
Figure 124 IP Application > DiffServ > DSCP Setting
DSCP Use this section to specify the DSCP values that you want to assign to packets based on
the color they are marked via TRTCM.
green Specify the DSCP value to use for packets with low packet loss priority.
yellow Specify the DSCP value to use for packets with medium packet loss priority.
red Specify the DSCP value to use for packets with high packet loss priority.
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.
