priority
Sets the scheduler as a strict priority.
Syntax
priority
Parameters None
Default WDRR — when priority is mentioned, it moves to SP with default level 1.
Command Mode POLICY-MAP-CLASS-MAP
Usage
Information
If you use this command, bandwidth is not allowed. Only the egress QoS policy type supports this
command.
Example
OS10(config-pmap-c-que)# priority
Supported
Releases
10.2.0E or later
priority-flow-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 flow-control on a interface, verify a matching network-qos type policy is
configured with the pfc-cos value for an interface. Use this command to disable priority flow-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
Configures a dot1p trust map to the traffic class.
Syntax
qos-group tc-list [dot1p values]
Parameters
● qos-group tc-list — Enter the traffic 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 define dot1p values to any traffic class, those flows map to the default traffic
class 0. If some of the dot1p values are already mapped to an existing traffic class, you see an error. You
must have a 1:1 dot1p-to-traffic 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
