35.4 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.

Commit
Rate

Specify the Commit Information Rate (CIR) for this port.

Peak
Rate

Specify the Peak Information Rate (PIR) for this port.

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.
