The color modes include “Color-Blind” which assumes that the packet
stream is uncolored, and “Color-Aware” which assumes that the incoming
packets are pre-colored. The functional differences between these modes
is described at the beginning of this section under “trTCM Police Meter.”
■
Committed Information Rate (CIR) – Committed rate in kilobits per
second. (Range: 0-10000000 kilobits or maximum port speed,
whichever is lower)
The rate cannot exceed the configured interface speed.
■
Committed Burst Size (BC) – Committed burst in bytes.
(Range: 4000-16000000 bytes)
The burst size cannot exceed 16 Mbytes.
■
Peak Information Rate (PIR) – Rate in kilobits per second.
(Range: 0-10000000 kbps or maximum port speed, whichever is lower)
The rate cannot exceed the configured interface speed.
■
Peak Burst Size (BP) – Burst size in bytes. (Range: 4000-128000000
bytes)
The rate cannot exceed the configured interface speed.
■
Conform – Specifies that traffic conforming to the committed
maximum rate (CIR) and peak burst size (BC) will be transmitted
without any change to the DSCP service level.
■
Set IP DSCP – Decreases DSCP priority for out of conformance
traffic. (Range: 0-63).
■
Transmit – Transmits in-conformance traffic without any change to
the DSCP service level.
■
Exceed – Specifies whether traffic that exceeds the committed
maximum rate (CIR) or committed burst size (BC) but is within the peak
information rate (PIR) will be dropped or the DSCP service level will be
reduced.
■
Set IP DSCP – Decreases DSCP priority for out of conformance
traffic. (Range: 0-63).
■
Drop – Drops out of conformance traffic.
■
Violate – Specifies whether the traffic that exceeds the peak
information rate (PIR) will be dropped or the DSCP service level will be
reduced.
■
Set IP DSCP – Decreases DSCP priority for out of conformance
traffic. (Range: 0-63).
■
Drop – Drops out of conformance traffic.
