actions defined by this command to transmit, remark the DSCP service
value, or drop a packet, the switch will also mark the two color bits used to
set the drop precedence of a packet for Random Early Detection.
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: 0-1000000 kbps at a granularity of 64 kbps
or maximum port speed, whichever is lower)
The rate cannot exceed the configured interface speed.
■
Committed Burst Size (BC) – Committed burst in bytes.
(Range: 0-16000000 bytes at a granularity of 4k bytes)
The burst size cannot exceed 16 Mbytes.
■
Peak Information Rate (PIR) – Rate in kilobits per second.
(Range: 0-1000000 kbps at a granularity of 64 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: 0-16000000
bytes at a granularity of 4k bytes)
The burst size cannot exceed 16 Mbytes.
■
Conform – Specifies that traffic conforming to the maximum
committed rate (CIR) and committed burst size (BC) will be
transmitted without any change to the DSCP service level.
■
Transmit – Transmits in-conformance traffic without any
change to the DSCP service level.
■
Exceed – Specifies whether traffic that exceeds the maximum
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).
