pause [buffer-size size pause-threshold xoff-size resume-threshold xon-
size]
Parameters

buffer in KB.

○ Default values for LLFC: 10G,25G–198.5KB, 40G,100G–264.5KB
● resume-threshold xon-size — (Optional) Enter the buffer limit for the port to stop or cancel
sending a pause to the peer in KB .

Command Mode POLICY-MAP-CLASS-MAP
Usage
Information
This command can only be used under network-qos policy type. Buffer-size, pause-thresholds, and
resume-thresholds vary based on platform. The no version of this command returns the value to the
default. Add the policy-map with pause to system-qos to service an input to enable pause on all ports,
based on a per-port link-level flow-control mode. The xoff and xon threshold settings for link-level flow-
control are applied on ports where all traffic classes must be mapped to a single PG. Platform-specific
default values are based on MTU sizes of 9216 and cable length of 100 meters.
Example
OS10(conf-pmap-c-nqos)# pause buffer-size 45 pause-threshold 25 resume-
threshold 10
