Set CoS – Sets a priority bits in the VLAN tag for matching packets.
n
(Range: 0-7)
Set IP DSCP – Configures the service provided to ingress traffic by
n
setting an IP DSCP value for a matching packet (as specified in rule
settings for a class map. (Range: 0-63)
Set IP Precedence – Configures the service provided to ingress
n
traffic by setting an IP Precedence 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
u
the action that results from a policy violation.
Meter Mode – Selects one of the following policing methods.
u
Flow (Police Flow) – Defines the committed information rate (CIR,
n
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
n
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.
n
(Range: 64-524288 bytes)
The burst size cannot exceed 16 Mbytes.
Conform – Specifies whether that traffic conforming to the
n
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
n
