Configuring QoS
Allocating Bandwidth Among Transmit Queues
To configure the transmit queue bandwidth, perform this task:
Command
Step 1
Switch(config)# interface gigabitethernet
slot/interface
Step 2
Switch(config-if)# tx-queue queue_id
Step 3
Switch(config-if-tx-queue)# [no] [bandwidth rate
| percent percent ]
Step 4
Switch(config-if-tx-queue)# end
Step 5
Switch# show qos interface
The bandwidth rate varies with the interface.
Bandwidth can only be configured on these interfaces:
•
•
•
•
•
This example shows how to configure the bandwidth of 1 Mbps on transmit queue 2.
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# interface gigabitethernet 1/1
Switch(config-if)# tx-queue 2
Switch(config-if-tx-queue)#bandwidth 1000000
Switch(config-if-tx-queue)# end
Switch#
Configuring Traffic Shaping of Transmit Queues
To guarantee that packets transmitted from a transmit queue do not exceed a specified maximum rate,
perform this task:
Command
Step 1
Switch(config)# interface {fastethernet |
gigabitethernet | tengigabitethernet}
slot/interface
Step 2
Switch(config-if)# tx-queue queue_id
Step 3
Switch(config-if-tx-queue)# [no] [shape rate |
percent percent ]

End with CNTL/Z.
Purpose
Selects the interface to configure.
Selects the transmit queue to configure.
Sets the transmit rate for the transmit queue.
Use the no keyword to clear the transmit queue maximum
rate.
