color-mode
Syntax
no color-mode {color-aware|color-blind}
Context
config>qos>sap-ingress>meter
Description
This command is used to configure the meter to operate in either color-aware mode or color-blind mode.
In color-blind mode, the profile/color assigned to the packet on ingress is ignored. The CIR and PIR rate
configured for the meter is used to determine the final color/profile for the packet. If the packet is within the
CIR, then the final profile/color assigned to the packet is in-profile/green and if the packets exceeds the CIR
and is within the PIR, then the final profile/color assigned to the packet is out-of-profile/yellow. Packets that
exceed the PIR rate are dropped.
In color-aware mode, the meter uses the profile assigned to the packet on ingress. Profile can be assigned on
ingress either by enabling DEI classification as done on access ports or by assigning profile based on either
Dot1p or DEI as done on network ports and access-uplink ports.
In color-aware mode, following behavior is available:

Parameters
color-mode — Specifies if the meter operates in color-aware or color-blind mode.
Values

no mbs
Context
config>qos>sap-ingress>meter
Description
This command provides the explicit definition of the maximum amount of tokens allowed for a specific
meter. The value is given in Kilobits and overrides the default value for the context.
In case of trtcm, the maximum burst size parameter specifies the maximum burst size that can be transmitted
by the source at the PIR while complying with the PIR. If the transmitted burst is lower than the MBS value
then the packets are marked as out-profile by the meter to indicate that the traffic is not complying with CIR,
but complying with PIR.
In case of srTCM, the MBS parameter specifies the maximum burst size that can be transmitted by the
source while not complying with the CIR. The transmitted burst is lower than the MBS value then the
packets are marked as out-profile by the meter to indicate that the traffic is not complying with CIR.

If the packet is pre-colored as in-profile (or also called as Green colored packets) then
depending on the burst size of the packet meter can either mark it in-profile or out-profile.
If the packet is pre-colored as out-profile (also called as Yellow colored packets) then even
if the packet burst is lesser than the current available CBS, it would not be marked as in-
profile and remain as out-profile.
If the packet burst is higher than the MBS then it would be marked as Red and would be
dropped by meter at ingress.
