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.

* 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
