Reference Guide
• pause-threshold kilobytes — Enter the threshold used to send pause frames in kilobytes to a
transmitting device (0 to 7787).
• resume-threshold kilobytes — Enter the threshold used to request a transmitting device in kilobytes
to resume sending trac (0 to 7787).
Defaults
The default ingress-buer size reserved for PFC trac classes, and the pause and resume thresholds vary
according to the interface type. The default egress buer reserved for PFC trac classes is 0 on all interface
types.

Command Mode POLICY-CLASS NETWORK-QOS
Usage Information Use the pause command without optional parameters to apply the default ingress-buer size, and pause (XON)
and resume (XOFF) thresholds. Default values for the buffer-size, pause-threshold, and resume-
threshold
parameters vary across interface types and port speeds. The default values are based on the default
MTU size of 9216 bytes. Use the optional queue-limit thresh-mode command to change the amount of
shared buers available to PFC trac-class queues in the policy-class-map.
Example
