Color mode Select how the policer treats packets that ingress with a CFI or DEI field
set to 1 (yellow). Options are:
Color Aware – All packets that ingress with a CFI/DEI field set to 1
(yellow) are treated as EIR packets, even if credits remain in the CIR
bucket.
Color Blind – All ingress packets are treated as green regardless of their
CFI/DEI value. A color-blind policer discards any former color decisions.
Coupling flag
Select Enable or Disable . When enabled, frames that ingress as yellow
may be converted to green when there are no available yellow credits in
the EIR bucket.
Coupling Flag is only relevant in Color Aware mode.
