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 mode
Command History
Usage Guidelines This command is not supported on the Supervisor Engine 6-E and Catalyst 4900M chassis.
The bandwidth and shape rates cannot exceed the maximum speed of the interface.
The 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.
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.
