pfc-cos
Configures priority flow-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 flow-control to
enable, from 0 to 7.
NOTE: The range 0-7 is invalid. All other ranges, including 0-6 and 1-7 are valid.
Default Not configured
Command Mode POLICY-MAP-CLASS-MAP
Usage Information To configure link-level flow-control, do not configure pfc-cos for the matched class for this policy. Add the
policy-map with the pfc-cos configuration to system-qos to service an input to enable priority flow-control
behavior on all ports, based on a per-port Priority Flow-Control Enable mode. Add the policy-map with the pfc-
cos configuration to interface configurations to service at input and enable Priority Flow-Control on that
particular port, based on the port's Priority Flow-Control Enable mode. If you configure 40G to 10G mode on
interfaces and
pause (no drop) is enabled on system-qos, all queues may or may not drop traffic based on the
availability of buffers. The
no version of this command returns the value to the default.
