queue parameters for each queue may be overridden on the queue group with specific queue
parameters.
Each queue group supports the application of a scheduler-policy for the purpose of managing the
queues within the group into an aggregate SLA. The queues defined within the template may be
configured with parent scheduler defining the mapping of a queue to one of the schedulers within the
scheduler policy. Egress queue groups also support the agg-rate-limit parameter and the queues in the
egress template support the port-parent command. Each command is used for configuring egress port
virtual scheduling behavior.
Each queue group allows the application of an accounting policy and the ability to enable and disable
collecting statistics. The statistics are derived from the queue counters on each queue within the
queue group. The accounting policy defines which queue counters are collected and to which
accounting file they will be written.
A queue group does not have an administrative shutdown or no shutdown command. A queue group
is considered to be always ?p?once created.
When creating a queue group, the system will attempt to allocate queue resources based on the
queues defined in the queue group template. If the appropriate queue resources do not currently exist,
the queue group will not be created. Ingress port queue groups do not support the shared-queuing or
multipoint-shared queuing behavior.
When the queue group is created on a LAG (Link Aggregation Group), it must be created on the
primary port member. The primary port member is the port with the lowest port ID based on the slot,
MDA position and port number on the MDA. A queue group created on the primary LAG port will
be automatically created on all other port members. If a new port is being added to a LAG with an
existing queue group, the queue group must first be created on the port prior to adding the port to the
LAG. If the LAG queue group has queue overrides, the queue overrides must also be defined on the
port queue group prior to adding the port to the LAG.
A port queue group cannot be removed from the port when a forwarding class is currently redirected
to the group. All forwarding class redirections must first be removed prior to removing the queue
group.
Default none
Parameters group-name — The group-name parameter is required when executing the port queue-group
command. The specified group-name must exist as an ingress or egress queue group template
depending on the ingress or egress context of the port queue group. Only a single queue group
may be created on an ingress port. Multiple queue groups may be created on an egress port.
create — Keyword used to associate the queue group. The create keyword requirement can be
enabled/disabled in the environment>create context.
