Class Fair Hierarchical Policing (CFHP)
Quality of Service Guide 875
Default no description
Parameters description string — The description-string parameter defines the ASCII description string for the
policer control policy. The description string can be up to 80 characters. If the string contains
spaces, it must be placed within beginning and ending double quotation marks. Beginning and
ending quotation marks are not considered part of the description string. Only printable
ASCII characters are allowed in the string. The sting does not need to be unique and may be
repeated in the descriptions for other policer control policies or other objects. If the command
is executed without the description-sting present, any existing description string will be
unaffected.
Default None
root
Syntax root
Context config>qos>policer-control-policy
Description The root node contains the policer control policies configuration parameters for the root arbiter.
Within the node, the parent policer’s maximum rate limit can be set and the strict priority level shared
and fair threshold portions may be defined per priority level.
The root node always exists and does not need to be created.
Default None.
max-rate
Syntax max-rate {kilobits-per-second | max}
no max-rate
Context config>qos>policer-control-policy>root
Description The max-rate command defines the parent policer’s PIR leaky bucket’s decrement rate. A parent
policer is created for each time the policer-control-policy is applied to either a SAP, or subscriber
instance for the 7450 ESS and 7750 SR, or multi-service site instance for the 7950 XRS. Packets that
are not discarded by the child policers associated with the SAP or subscriber or multi-service site
instances are evaluated against the parent policer’s PIR leaky bucket.
