mtu
Calculates the buffer size allocation for matched flows.
Syntax
mtu size
Parameters size — Enter the size of the buffer (1500 to 9216).
Default 9216
Command Mode POLICY-MAP-CLASS-MAP
Usage Information The no version of this command returns the value to the default.
Example
OS10(conf-pmap-nqos-c)# mtu 2500

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 See parameter values
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.
