pfc-cos
Congures priority ow-control for cost of service (CoS).
Syntax
pfc-cos cos-value
Parameters cos-value — Enter a single, comma-delimited, or hyphenated range of CoS values for priority ow-control to
enable (0 to 7).
Default Not congured
Command Mode POLICY-MAP-CLASS-MAP
Usage Information To congure link-level ow-control, do not congure pfc-cos for the matched class for this policy. Add the
policy-map with the pfc-cos conguration to system-qos to service an input to enable priority ow-control
behavior on all ports, based on a per-port priority ow-control enable mode. Add the policy-map with the
pfc-
cos conguration to interface congurations to service at input to enable priority ow-control on that particular
port, based on the port's priority ow-control enable mode. If you congure 40G to 10G mode on interfaces and
pause (no drop) is enabled on system-qos, all queues may or may not drop trac based on the availability of
buers. The no version of this command returns the value to the default.
Example
OS10(conf-pmap-c-nqos)# pfc-cos 0-2
Example (global
buer/shared
buer)
OS10(config)# policy-map type network-qos nqGlobalpolicy1
OS10(conf-cmap-nqos)# class CLASS-NAME
OS10(conf-cmap-nqos-c)# pause buffer-size 45 pause-threshold 25 resume-

pfc-max-buer-size
Congures the maximum buer size for the priority ow-control enabled ows.
Syntax
pfc-max-buffer-size max-buffer-size
Parameters max-buffer-size — Enter the maximum buer size in KB.
Default None
Command Mode SYSTEM-QOS
Usage Information This command congures maximum size of the lossless buer pool.. The no version of this command removes the
maximum buer size limit.
Example
OS10(config-sys-qos)# pfc-max-buffer-size 2000
