Understanding QoS Configuration on the Matrix N-Series
• virtual queues 12‐15 to physical queue 3
• virtual queues 8‐11 map to physical queue 2
• virtual queues 4‐7 map to physical queue 1
• virtual queues 0‐3 map to physical queue 0
The TxQ reference table can be displayed using the show cos reference txq command and
displays port‐group, reference index, and physical queue.
The following example displays default values for the show cos reference txq command output:
Matrix(su)->show cos reference txq

Although the TxQ reference table is populated by default, the Queue‐to‐Reference mapping can
be configured using the set cos reference txq command. You need to:
• Identify the port group for configuration
• Identify the transmit queue reference, along with the associated queue
