Syntax
pause [buffer-size size pause-threshold xoff-size resume-threshold xon-size]
Parameters
  • buffer-size size — (Optional) Enter the ingress buffer size which is used as a guaranteed buffer 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
Example (global and shared buffer)
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 30 resume-threshold 30
                                       
                                    
OS10(config)# policy-map type network-qos nqGlobalpolicy1
                                       OS10(conf-cmap-nqos)# class type network-qos nqclass1
                                       OS10(conf-cmap-nqos-c)# pause buffer-size 45 pause-threshold 30 resume-threshold 10
