# traffic-class-group

#### Syntax

[ no ] traffic-class-group trafficClassGroupName
[ slot slotNumber | auto-strict-priority | extended ]

#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

Configures a traffic-class group. The no version deletes the selected traffic-class group. You must remove all local (slot-based) instances of a traffic-class group before you can remove the global group.

#### Options

- trafficClassGroupName—Name of the traffic class group; up to 31 characters
- slotNumber—Number of the slot associated with the group, in the range 0—17
- auto-strict-priority—Specifies strict-priority scheduling for the group, regardless of whether the scheduler profile associated with the group node specifies strict-priority scheduling. Only one auto-strict-priority group can exist; this is the default behavior for a group.
- extended—Specifies that strict-priority scheduling for the group is determined by the scheduler profile associated with the group node; scheduling is either hierarchical round-robin or strict priority, but if a strict-priority traffic-class group already exists, this group must scheduled via HRR
