For T-series and M320 platforms with Enhanced II Flexible PIC Concentrators (FPCs), you can configure single-rate or two-rate tricolor marking (TCM).
TCM extends the functionality of class-of-service (CoS) traffic policing by providing three levels of drop priority instead of two. This allows you to provision more enhanced service-level agreements (SLAs) across the Differentiated Services (DiffServ) domain by defining tricolor marking policers, and three levels of packet loss priority (PLP) for classifiers, rewrite rules, random early detection (RED) drop profiles, and firewall filters.
The color of a packet, as used or set by a tricolor marking policer, corresponds to the packet’s drop precedence (loss priority or PLP). Packets with high PLP are marked red, packets with medium PLP are marked yellow, and packets with low PLP are marked green.
The following sections describe tricolor marking policers:
