Enabling Tricolor Marking

By default, TCM is enabled on M120 and MX Series routers. To enable TCM on other routers, include the tri-color statement at the [edit class-of-service] hierarchy level:

[edit class-of-service]tri-color;

This statement is necessary on the following routers:

M320 and T Series routers with Enhanced II FPCs
T640 routers with Enhanced Scaling FPC4s

If you do not include this statement in the configuration on platforms that require it, you cannot configure medium-low or medium-high PLP for classifiers, rewrite rules, drop profiles, or firewall filters.
