Understanding Color-Blind Mode for Single-Rate Tricolor Marking
With the color-blind mode of single-rate tricolor marking, all packets are evaluated against the CBS. If a packet exceeds the CBS, it is evaluated against the EBS. In color-blind mode, the policer supports three loss priorities only: low, medium-high, and high.
Packets that exceed the CBS but are below the EBS are marked yellow (medium-high). Packets that exceed the EBS are marked red (high), as shown in Table 1.
