DSCP Mutation Map

On this page, users can view 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, as shown
below:
Description
Select the range of ports that will be used for this 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 8 and 10000000 kbps. Also enter the maximum bandwidth
(Max Bandwidth) rate limit in the space provided. This value must be
between 8 and 10000000 kbps.
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 (%).
