Page 16-16
Parameter Input Type Permitted Values Description
profile-id Number 1 – 250 A unique ID for the rate meter (policer)
profile.
cir Number
0, or 64,000 -
1,000,000,000 The Committed Information Rate (CIR)
defined for the rate meter (policer), in bits
per second.
If the value is 0, all incoming CIR traffic is
dropped.
cbs Number 0 - 128 The Committed Burst Rate (CBR) for the
rate meter (policer), in Kbytes.
eir Number
0, or 64,000 -
1,000,000,000 The Excess Information Rate (EIR) for the
rate meter (policer), in bits per second.
If the value is 0, all incoming EIR traffic is
dropped.
ebs Number 0 - 128 The Excess Burst Rate (EBR) for the rate
meter (policer), in Kbytes.
color-mode Variable color-blind
color-aware Determines how the rate meter (policer)
treats frames that ingress with a CFI or DEI
field set to 1 (yellow). Options are:
color aware
– All frames that ingress
with a CFI/DEI field set to 1 (yellow) are
treated as EIR frames, even if credits
remain in the CIR bucket.
color blind
– All ingress frames are
treated as green regardless of their
CFI/DEI value. A color-blind policer
discards any former color decisions.
coupling-flag Variable enable
disable When enabled, frames that ingress as
yellow may be converted to green when
there are no available yellow credits in the
EIR bucket. Only relevant in
color-
aware
mode.
rate-meter-
profile-name Text string Up to 20 characters. A description of the rate meter (policer)
profile.
The following command creates a rate meter (policer) profile with Profile ID 50, named “64k.”
