Usage Guideline
Use this command to configure the minimal and maximum bandwidth for a specified queue. When the
minimal bandwidth is configured, the packet transmitted from the queue can be guaranteed. When the
maximum bandwidth is configured, packets transmitted from the queue cannot exceed the maximum
bandwidth even if the bandwidth is available.
When configuring the minimal bandwidth, the aggregate of the configured minimum bandwidth must
be less than 75 percent of the interface bandwidth to make sure the configured minimal bandwidth
can be guaranteed. It is not necessary to set the minimum guaranteed bandwidth for the highest strict
priority queue. This is because the traffic in this queue will be serviced first if the minimal bandwidth of
all queues is satisfied.
The configuration of this command can only be attached to a physical port but not a port-channel.
That is the minimum guaranteed bandwidth of one CoS cannot be used across physical ports.
Example
This example shows how to configure the queue bandwidth, the minimum guaranteed bandwidth and
maximum bandwidth of queue 1 of interface eth3/0/1 to 100Kbps and 2000Kbps respectively. Set the
minimum guaranteed bandwidth and maximum bandwidth of queue 2 to 10% and 50% respectively.
Switch# configure terminal
Switch(config)# interface eth3/0/1
Switch(config-if)# queue 1 rate-limit 100 2000
Switch(config-if)# queue 2 rate-limit percent 10 percent 50
Switch(config-if)#
56-19 rate-limit {input | output}
This command is used to set the received bandwidth limit values for an interface. To set the transmit
bandwidth limit values on an interface use the rate-limit output command in the interface
configuration mode. Use the no form of this command to disable the bandwidth limit.
Specifies the queue ID to set minimal guaranteed and maximum
bandwidth.
Specifies the minimal guaranteed bandwidth in kilobits per second
allocated to a specified queue.
Specifies the maximum bandwidth in kilobits per second for a
specified queue.
Specifies to set the minimal bandwidth by percentage. The valid
range is from 1 to 100.
Specifies to set the maximum bandwidth by percentage. The valid
range is from 1 to 100.
