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 based on the availability of buers.
The no version of this command returns the value to the default.
