36.4 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.
Port 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.
Note: Changes in this row are copied to all the ports as soon as you
make them.
Active Select this to activate TRTCM on the port.
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.
