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. - Default values for PFC: 10G-166KB, 25G-195.5KB, 40G-315.5KB, 100G-512KB - Default values for LLFC: 10G,25G- 234.5KB, 40G,100G-339.5KB • 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 for PFC: 10G-96KB, 25G-96KB, 40G-192KB, 100G-232KB - 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 . - Default values for PFC: 10G-87KB, 25G-87KB, 40G-183KB, 100G-223KB - Default values for LLFC: 10G,25G-9KB, 40G,100G-36KB Default Command Mode Usage Information Example See parameter values POLICY-MAP-CLASS-MAP This command can only be used under network-qos policy type. Buffer-size, pause-thresholds, and resumethresholds 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 linklevel 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.
