Setting Up a CoS Profile Configuration Job
A CoS profile is used to map an input frame to a Layer 2 class of service based on the conformance level (Green/Yellow) of the incoming traffic and on the value of the following information for the incoming frames:
- PCP: p-bits in 802.1Q / 802.1Q-in-Q tags.
- IP Precedence: IP precedence bits in the IPv4 ToS byte or in the IPv6 Traffic Class byte.
- DSCP: DSCP bits in the IPv4 ToS byte or in the IPv6 Traffic Class byte.
