Definition
Profile ID
A unique ID for the policer profile. You can choose from any
unused value from 1 to 250. Once you have added the profile,
you cannot change the Profile ID.
Description
A description of the policer profile.
Policer type
Read-only. The type of policer. Always set to MEF-TRTCM.
CIR
Enter the Committed Information Rate (CIR) for the policer, in
bits per second. Permitted values are 0, or 64,000 through
1,000,000,000 bps. If the value is 0, all incoming CIR traffic is
dropped.
CBS
Enter the Committed Burst Rate (CBR) for the policer, in Kbytes.
Permitted values are 2 through 128 Kbytes.
EIR
Enter the Excess Information Rate (EIR) for the policer, in bits
per second. Permitted values are 0, or 64,000 through
1,000,000,000 bps. If the value is 0, all incoming EIR traffic is
dropped.
EBS
Enter the Excess Burst Rate (EBR) for the policer, in Kbytes.
Permitted values are 2 through 128 Kbytes.
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.
Editing a Policer Profile
To edit a policer profile, select the profile in the Police Profile table and click Edit. The Policer
Profile Table Edit page opens.
The Policer Profile Table - Edit page is identical to the Policer Profile Table - Add page (

the Profile ID.
