Purpose
Eight transmit queues are implemented in the switch hardware for each port. The commands in
this section allow you to set the priority mode and weight for each of the available queues (0
through 5) for each physical port on the switch.
Priority queues 6 and 7 are reserved for stacking and control protocols and are run in strict
priority. They cannot be modified by the set port txq or clear port txq commands. Their settings
are displayed by the show port txq command.
Priority mode and weight cannot be configured on LAGs, only on the physical ports that make up
the LAG.
Commands
show port txq
Use this command to display QoS transmit queue information for one or more physical ports.
Syntax
show port txq [port-string]
Parameters
Defaults
If the port-string is not specified, the QoS setting of all physical ports will be displayed.
Mode
Switch command, read-only.

port-string (Optional) Specifies port(s) for which to display QoS settings. For a
detailed description of possible port-string values, refer to “Port String
Syntax Used in the CLI” on page 11-1.
Only physical ports will be displayed. LAG ports have no transmit queue
information.
