Configuring CoS Reference Mapping

The CoS Reference Table maps the TxQ, ORL, 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. ORL is supported on the S- and K-Series. 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.
