Parameter
Description
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.
•
When the
Min Percent
option is selected, enter the minimum
bandwidth percentage value in the space provided. This value must be
between 1 and 100 percent (%). Also enter the maximum percentage
value (
Max Percent
) in the space provided. This value must be
between 1 and 100 percent (%).

DSCP Mutation Map
This window is used to display and configure the Differentiated Services Code Point (DSCP) mutation map settings.
When a packet is received by an interface, based on a DSCP mutation map, the incoming DSCP can be mutated to
another DSCP immediately before any QoS operations. The DSCP mutation is helpful to integrate domains with
different DSCP assignments. The DSCP-CoS map and DSCP-color map will still be based on the packet’s original
DSCP. All the subsequent operations will base on the mutated DSCP.
To view the following window, click
QoS > Advanced Settings > DSCP Mutation Map
