Usage
Information
You cannot enter two match statements with the same filter-type. If you enter two match statements
with the same filter-type, the second statement overwrites the first statement.
Example
OS10(conf-cmap-qos)# match vlan 100
Supported
Releases
10.2.0E or later
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
Supported
Releases
10.3.0E or later
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 for PFC: 10G, 25G183KB, 40G375KB, 100G446KB
Default values for LLFC: 10G,25G207.5KB, 40G,100G300.5KB
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, 25G96KB, 40G192KB, 100G232KB
Default values for LLFC: 10G,25G198.5KB, 40G,100G264.5KB
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, 25G87KB, 40G183KB, 100G214KB
Default values for LLFC: 10G,25G9KB, 40G,100G36KB

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 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
