LABEL DESCRIPTION
Active 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.
Mode 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.
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.
