31.4 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.

DESCRIPTION
Select this to activate TRTCM (Two Rate Three Color Marker) on the Switch. The
Switch evaluates and marks the packets based on the TRTCM settings.
Note: You must also activate DiffServ on the Switch and the individual
ports for the Switch to drop red (high loss priority) colored packets.
Select color-blind to have the Switch treat all incoming packets as uncolored.
All incoming packets are evaluated against the CIR and PIR.
Select color-aware to treat the packets as marked by some preceding entity.
Incoming packets are evaluated based on their existing color. Incoming packets
that are not marked proceed through 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.
Note: Changes in this row are copied to all the ports as soon as you make
them.
Select this to activate TRTCM on the port.
Specify the Commit Information Rate (CIR) for this port.
Specify the Peak Information Rate (PIR) for this port.
Use this section to specify the DSCP values that you want to assign to packets
based on the color they are marked via TRTCM.
Specify the DSCP value to use for packets with low packet loss priority.
Specify the DSCP value to use for packets with medium packet loss priority.
Specify the DSCP value to use for packets with high packet loss priority.
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.
