Creating QoS Policies
Violate – Specifies whether the traffic that exceeds the
maximum rate (CIR) 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.
srTCM (Police Meter) – Defines the committed information rate
(CIR, or maximum throughput), committed burst size (BC, or burst
rate) and excess burst size (BE), and the action to take for traffic
conforming to the maximum throughput, exceeding the maximum
throughput but within the excess burst size, or exceeding the
excess burst size. In addition to the 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 prioritize
service to packets of different colors.
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 "srTCM Police Meter."
Committed Information Rate (CIR) – Rate in kilobits per
second. (Range: 1-1000000 kbps or maximum port speed,
whichever is lower)
The rate cannot exceed the configured interface speed.
Committed Burst Size (BC) – Burst in bytes.
(Range: 64-524288 bytes)
The burst size cannot exceed 16 Mbytes.
Exceeded Burst Size (BE) – Burst in excess of committed
burst size. (Range: 64-524288 bytes)
The burst size cannot exceed 16 Mbytes.
Conform – Specifies whether that traffic conforming to the
maximum rate (CIR) will be transmitted without any change to
the DSCP service level, or if the DSCP service level will be
modified.
Transmit – Transmits in-conformance traffic without any
change to the DSCP service level.
Set IP DSCP – Modifies DSCP priority for in-conformance
traffic. (Range: 0-63)
