QoS Policy Generation
Bandwidth Allocation
This area allows you to track and allocate bandwidth to the outgoing traffic.This
column also lists the bandwidth remaining after allocating bandwidth to each
traffic type going out on the selected interface.
Note At least one traffic type has to be selected to generate the QoS policy.
Type of Traffic
This column list the type of traffic exiting the selected interface. The three traffic
types are: Real-Time, Business-Critical, and Best-Effort.
Bandwidth in %
Enter bandwidth values in the Bandwidth in % field. SDM recommends 72% of
available bandwidth allocation for real-time traffic and 3%of available
bandwidth for business-critical traffic.
Note The Cisco IOS software does not allow you to allocate more than 75% of the total
interface bandwidth to one or more QoS classes.
SDM dynamically adjusts the value for Best-Effort traffic when you enter values
for Real Time or Business-Critical so that the total bandwidth is always 100%.
kbps value
This column displays the bandwidth allocated to each type of traffic in
kilo bits per second(k bps) units. This field is read-only and is automatically
updated based on the percentage value entered in the Bandwidth in % field.
View Details
Click on the View Details button if you want to check QoS classes created for the
selected traffic type. SDM will generate default QoS policy consisting of
pre-defined QoS classes for each traffic type. See View QoS Class Details to learn
