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.
