tx-queue

To configure the transmit queue parameters for an interface, use the tx-queue command. To return to the

default value, use the no form of this command.

tx-queue [queue-id] {bandwidth bandwidth-rate | priority high | shape shape-rate}

no tx-queue

Syntax Description

Defaults The default settings are as follows:

• Encapsulation type is dependent on the platform or interface hardware.

• QoS enabled bandwidth rate is 4:255.

• QoS disabled bandwidth rate is 255:1.

Command Modes Interface configuration

Command History

Usage Guidelines The bandwidth and shape rates cannot exceed the maximum speed of the interface.

Bandwidth can be configured only on the following:

• Uplink ports on Supervisor Engine III (WS-X4014)

• Ports on the WS-X4306-GB module

• The two 1000BASE-X ports on the WS-X4232-GB-RJ module

• The first two ports on the WS-X4418-GB module

• The two 1000BASE-X ports on the WS-X4412-2GB-TX module

Only transmit queue 3 can be configured to be a high-priority transmit queue.

Examples This example shows how to allocate bandwidth on queue 1 to 100 MBPS:

Switch(config-if)# tx-queue 1

queue-id (Optional) Number of the queue; valid values are from 1 to 4.

bandwidth bandwidth-rate Specifies traffic bandwidth; valid values are from 16000 to

1000000000 bits per second.

priority high Specifies high priority.

shape shape-rate Specifies the maximum rate that packets are passed through a

transmit queue; valid values are from 16000 to 1000000000 bits per

second.

Release Modification

12.1(8a)EW Support for this command was introduced on the Catalyst 4500 series switch.
