Creating QoS Policies
• Committed Burst Size (BC) – Burst in bytes. (Range: 0-16000000 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 at a granularity of 4k
bytes)
The burst size cannot exceed 16 Mbytes.
• Conform – Specifies that traffic conforming to the maximum rate (CIR) 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 rate (CIR) 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.
