No violators exist for this/these irl(s)
The set cos port‐resource irl command is used for creating inbound rate limiters. You need to:
• Identify the port group for configuration
• Identify the limiter resource ID, along with desired unit, rate, and actions
Configuring CoS Reference Mapping
The CoS Reference Table maps the TxQ and IRL references, defined by you and configured in the
CoS Settings Table, to physical queues and rate limiters created in the port‐resource table. A CoS
reference table exists for each port group. The CoS reference table indexes can be thought of as
virtual queues or rate limiters. The table accounts for the maximum number of queues and rate
limiters supported by the device. The virtual queues and limiters map to the physical queues and
rate limiters. The TxQ Reference Table is populated by default, because queues are required for
all forwarding. The TxQ reference maps each reference value to a physical queue. The IRL
Reference Table is not configured by default, because inbound rate limiting is optional.
CoS TxQ Reference Mapping
The CoS TxQ reference table uses 16 indexes or virtual queues, and maps each to a physical queue
or resource. A TxQ reference table exists for each port group configured and is indexed similarly
to port‐resources, as port‐group.port‐type reference. For port‐types with 16 queues, the 16‐txq
reference indexes map directly to the 16 physical queues. For port‐types with 4 queues, the 16‐txq
reference indexes map:
