See Table 11-5: "Default Mapping of CoS/CFI to Internal PHB/Drop
Precedence" on page
• Set PHB – Configures the service provided to ingress traffic by setting the
internal per-hop behavior for a matching packet (as specified in rule settings for
a class map). (Range: 0-7)
See Table 11-4: "Default Mapping of DSCP Values to Internal PHB/Drop Values"
on page 11-10).
• Set IP DSCP – Configures the service provided to ingress traffic by setting an IP
DSCP value for a matching packet (as specified in rule settings for a class
map). (Range: 0-63)
• Meter – Check this to define the maximum throughput, burst rate, and the action
that results from a policy violation.
• Meter Mode – Selects one of the following policing methods.
• Flow (Police Flow) – Defines the committed information rate (CIR, or maximum
throughput), committed burst size (BC, or burst rate), and the action to take for
conforming and non-conforming traffic. Policing is based on a token bucket,
where bucket depth (that is, the maximum burst before the bucket overflows) is
specified by the "burst" field, and the average rate tokens are removed from the
bucket is by specified by the "rate" option.
• Committed Information Rate (CIR) – Rate in kilobits per second. (Range:
64-1000000 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) – Burst in bytes. (Range: 4000-16000000 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.
• 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.
