pfc-shared-headroom-buer-size
Congures the shared headroom size for absorbing the packets after pause frames are generated.
NOTE: This command is available only on Z9100-ON and HE-IOM.
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 (1 to 3399).
Default 1024 KB
Command Mode SYSTEM-QOS
Usage Information This command is used to congure the shared headroom size. All PFC enabled priority groups can use the shared
headroom space. Headroom is the buer space which absorbs the incoming packets after the PFC frames reach
the sender. Once the threshold is reached PFC frames are generated towards the sender. The packets sent by the
sender after the PFC frames are generated 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 (0 to 4000000).
• bc committed-burst-size — (Optional) Enter committed burst size in packets for control plane policing
and in KB for data packets. (16 to 200000).
• pir peak-rate — Enter a peak-rate value in kilo bits per second (0 to 40000000).
• be peak-burst-size — (Optional) Enter a peak burst size in kilo bytes (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
