Add Rule
Policy Name – Name of policy map.
Class Name – Name of a class map that defines a traffic classification
upon which a policy can act.
Action – This attribute is used to set an internal QoS value in hardware
for matching packets. The PHB label is composed of five bits, three bits
for per-hop behavior, and two bits for the color scheme used to control
queue congestion with the srTCM and trTCM metering functions.
Set CoS – Configures the service provided to ingress traffic by
setting an internal CoS value for a matching packet (as specified in
rule settings for a class map). (Range: 0-7)
See
Table 18, "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 17, "Default Mapping of DSCP Values to Internal PHB/
Drop Values," on page
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.
