DESCRIPTION

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

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.

 

 

32.4 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.
