Understanding QoS Configuration on the Matrix N-Series
Port-Groups: TxQ Configuration
TxQ Port‐Groups contain user settings for specific types of ports and their matching transmit
queue settings. Port groups 0.0 and 0.1 exist by default. New port groups can be configured with a
name and ports can be added according to device port‐type. Transmit queue behavior can also be
configured per port group; port‐groups 0.0 and 0.1 are configured in strict queuing mode.
Additional port groups also default to strict queuing mode, though each TxQ port group can be
configured for weighted‐fair queuing if desired.
The show cos port‐config txq command displays all configured TxQ port‐groups. Group name
and type are displayed as well as ports associated with the port group. For show cos port‐config
txq output, arbiter mode (TxQ mode) is displayed along with a picture of the supported queues
and the number of slices allotted to the group. Queuing is also displayed by percentage.
The following example displays default values for the show cos port‐config txq command output:
Matrix(su)->show cos port-config txq
* Percentage/queue (if any) are approximations based on
[(slices/queue) / total number of slices]

Additional port groups can be created using the set cos port‐config txq command. Name and
associated ports can be configured, as well as TxQ settings. You need to:
