Trtcm Commands - ZyXEL Communications XS3800-28 Cli Reference Manual

This chapter explains how to use commands to configure the Two Rate Three Color Marker (trTCM)
feature on the Switch.
94.1 trTCM Overview
Two Rate Three Color Marker (trTCM, defined in RFC 2698) is a type of traffic policing that identifies
packets by comparing them to two user-defined rates: the Committed Information Rate (CIR) and the
Peak Information Rate (PIR). trTCM then tags the packets:
• red - if the packet exceeds the PIR
• yellow - if the packet is below the PIR, but exceeds the CIR
• green - if the packet is below the CIR
The colors reflect the packet's loss priority and the Switch changes the packet's DiffServ Code Point
(DSCP) value based on the color.
