pause

Enables a pause based on buffer limits for the port to start or stop communication to the peer.

Syntax
pause [buffer-size size pause-threshold xoff-size resume-threshold xon-size]
Parameters
  • buffer-size size — (Optional) Enter the ingress buffer size used as a guaranteed buffer in KB, default values: 10G–45KB, 40G–93KB.
  • pause-threshold xoff-size — (Optional) Enter the buffer limit for the port to start or initiate a pause to the peer in KB, default values: 10G–9KB, 40G–18KB.
  • resume-threshold xon-size — (Optional) Enter the buffer limit for the port to stop or cancel sending a pause to the peer in KB (defaults 10G–9KB, 40G–9KB).
Default

Command Mode
POLICY-MAP-CLASS-MAP
Usage Information
Only use this command under the network-qos policy type. Buffer-size, pause-thresholds, and resume-thresholds vary based on platform. 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 or Priority Flow-Control enable 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. The no version of this command returns the value to the default.
Example
OS10(conf-pmap-c-nqos)# pause buffer-size 45 pause-threshold 25 resume-threshold 10
