Description
Select the switch unit that will be used for this configuration here.
Select the appropriate port range used for the configuration here.
Select the queue ID that will be configured here. Options to choose
from are 0 to 7.
Select and enter the queue rate limit settings here.
When the Min Bandwidth option is selected, enter the minimum
bandwidth rate limit value in the space provided. This value must be
between 64 and 10000000 kbps. Also enter the maximum bandwidth
(Max Bandwidth) rate limit in the space provided. This value must be
between 64 and 10000000 kbps. The granularity is 64.
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.
