Queue Sharing and Redirection

Port Queue Groups

Once an ingress or egress queue group template is defined, a port based queue group with the
same name may be created. Port queue groups are named objects that act as a container for a
group of queues. The queues are created based on the defined queue IDs within the associated
queue group template. Port queue groups must be created individually on the ingress and
egress sides of the port, but multiple port queue groups of the same template name may be
created on egress ports if they have a different instance identifier. These are termed 'queue
group instances'. Each instance of a named queue group created on a port is an independent
set of queues structured as per the queue group template. Port queue groups are only
supported on Ethernet ports and may be created on ports within a LAG.

Percent-Rate Support

The percent-rate command is supported in a queue group template for pir and cir parameters
only for egress queues. The user has the option of specifying percent-rate for pir and cir
parameters. For pir, the range is 0.01 to 100.00, and for cir, the range is 0.00 to 100.00.
The rate can be also configured using the existing keyword rate in Kbps.
When the queue rate is configured with percent-rate, a port-limit is applied, specifically, the
percent-rate is relative to the rate of the port to which the queue is attached.

Forwarding Plane Queue Groups

Ingress forwarding plane queue groups allow groups of SAPs on one or more ports, or on a
LAG on the IOM, IMM, or XMA, to be bundled together from a QoS enforcement
perspective with an aggregate rate limit to be enforced across all SAPs of a bundle. Multiple
queue groups are supported per IOM/IMM/XMA or port on access ingress. These are
implemented at the forwarding plane level on the ingress IOM so that SAPs residing on
different ingress ports or SAPs on a LAG spread across ports on a given IOM can be
redirected to the same queue group
