towards the sender. The packets sent by the sender after the PFC frames generate are absorbed into the
Headroom buer. The no version of this command returns the value to the default.
Example
OS10(conf-sys-qos)# pfc-shared-headroom-buffer-size 2000
Supported Releases 10.4.0E(R1) or later
police
Congures trac policing on incoming trac.
Syntax
police {cir committed-rate [bc committed-burst-size]} {pir peak-rate [be peak-
burst-size]}
Parameters
• cir committed-rate — Enter a committed rate value in kilo bits per second, from 0 to 4000000.
• bc committed-burst-size — (Optional) Enter the committed burst size in packets for control plane
policing and in KB for data packets, from 16 to 200000.
• pir peak-rate — Enter a peak-rate value in kilo bits per second, from 0 to 40000000.
• be peak-burst-size — (Optional) Enter a peak burst size in kilo bytes, from 16 to 200000.
Defaults
• bc committed-burst-size value is 200 KB for control plane and 100 KB for all other class-map
types
• be peak-burst-size value is 200 KB for control plane and 100 KB for all other class-map types
Command Mode POLICY-MAP-CLASS-MAP
Usage Information If you do not provide the peak-rate pir values, the committed-rate cir values are taken as the pir values. Only
the ingress QoS policy type supports this command. For control-plane policing, the rate values are in pps.
Example
OS10(conf-pmap-c-qos)# police cir 5 bc 30 pir 20 be 40
Supported Releases 10.2.0E or later
policy-map
Enters QoS POLICY-MAP mode and creates or modies a QoS policy-map.
Syntax
policy-map policy-map-name [type {qos | queuing | control-plane | application |
network-qos }]
Parameters
• policy-map-name — Enter a class name for the policy-map. A maximum of 32 characters.
• type — Enter the policy-map type.
– qos — Create a qos policy-map type.
– queuing — Create a queueing policy-map type.
– control-plane — Create a control-plane policy-map type.
– application — Create an application policy-map type.
– network-qos — Create a network-qos policy-map type.
Defaults qos = class-map type and match-any = class-map lter
