Description This command creates an ingress or egress queue group on an Ethernet port. A queue group is a
collection of queues identified by a group name. Queue groups are used as an alternative queue
destination for SAPs or egress IP interfaces. Queue groups are not supported on HSMDA Ethernet
ports.
Within a SAP, a forwarding class may be redirected from the local SAP queue to a port queue group
queue. The forwarding classes from multiple SAPs may be redirected to the same queue group which
can be used to minimize the number of per-SAP queues.
Within a network IP interface, an egress forwarding class may be redirected from the port network
queue (created by the network-queue policy applied to the network port) to an egress port queue
group. The egress queue groups may be used to create queues per egress IP interface. In this case,
each IP interface would be mapped to a different queue group and the network QoS policy applied to
the IP interface will dictate which forwarding classes are redirected to the queue group. As an
alternative, multiple IP interfaces may share the same queue group.
Queue groups may be created on both access and network oriented ports. When the port is in access
mode, the queue groups must be created within the port access node. Queue groups on network mode
ports are created within the network node.
Within the access and network nodes, queue groups are also configured as ingress or egress. Access
ingress queue groups can only be used by ingress SAP forwarding classes and only a single ingress
queue group per port is supported. Multiple access egress queue groups may be created on a single
port and are used by egress SAP forwarding classes. On network mode ports, queue groups are only
supported on the egress side and are used by forwarding classes on egress IP interfaces.
When the queue group is created in an ingress port context, the group-name must be an existing
ingress queue group template. Similarly, queue groups created in an egress port context must have a
group-name of an existing egress queue group template. Two ingress queue groups with the same
name cannot be created on the same port. Two egress queue groups cannot be created on the same
port with the same name.
The queues defined in the template are created on the queue group. The queue parameters within the
template are used as the default queue parameters for each queue in the queue group. The default
