DXS-3600 Series Layer 3 Managed 10Gigabit Ethernet Switch CLI Reference Guide
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 Ethernet 1/0/1 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 ethernet 1/0/1
Switch(config-if)# queue 1 rate-limit 100 2000
Switch(config-if)# queue 2 rate-limit percent 10 percent 50
Switch(config-if)#
87-19 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. To disable the bandwidth limit, use the no form of this command.
rate-limit {input | output} {NUMBER-KBPS | percent PERCENTAGE} [BURST-SIZE]
