priority-ow-control mode
Enables or disables Priority Flow-Control mode on an interface.
Syntax
priority-flow-control mode [on]
Parameters
• on — (Optional) Enables Priority Flow-Control mode.
Default Disabled
Command Mode INTERFACE
Usage Information Before enabling priority ow-control on a interface, verify a matching network-qos type policy is congured with
the pfc-cos value for an interface. Use this command to disable priority ow-control if you are not using a
network-qos type policy for an interface. The no version of this command returns the value to the default.
Example
OS10(conf-if-eth1/1/2)# priority-flow-control mode on
Supported Releases 10.3.0E or later
qos-group dot1p
Congures a dot1p trust map to the trac class.
Syntax
qos-group tc-list [dot1p values]
Parameters
• qos-group tc-list — Enter the trac single value class ID, from 0 to 7.
• dot1p values — (Optional) Enter either single, comma-delimited, or a hyphenated range of dot1p values,
from 0 to 7.
Default 0
Command Mode TRUST-MAP
Usage Information If the trust map does not dene dot1p values to any trac class, those ows map to the default trac class 0. If
some of the dot1p values are already mapped to an existing trac class, you see an error. You must have a 1:1
dot1p-to-trac class mapping for PFC-enabled CoS values. You must also have a common dot1p trust map for all
interfaces using DCB. The no version of this command returns the value to the default.
Example
OS10(conf-tmap-dot1p-qos)# qos-group 5 dot1p 5
Supported Releases 10.3.0E or later
qos-group dscp
Congures a DSCP trust map to the trac class.
Syntax

Parameters
