Syntax
pfc-shared-headroom-buffer-size headroom-buffer-size
Parameters headroom-buffer-size — Enter the size of the priority ow-control headroom buer in KB, from 1 to 3399.
Default 1024 KB
Command Mode SYSTEM-QOS
Usage Information All PFC-enabled priority groups can use the shared headroom space. Headroom is the buer space that absorbs
the incoming packets after the PFC frames reach the sender. After the threshold is reached, PFC frames generate
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.
