304 Chapter 19 Bandwidth Management
19.3 Proportional Bandwidth Allocation
Bandwidth management allows you to define how much bandwidth each class gets; however,
the actual bandwidth allotted to each class decreases or increases in proportion to actual
available bandwidth.
19.4 Application-based Bandwidth Management
You can create bandwidth classes based on individual applications (like VoIP, Web, FTP, E-
mail and Video for example).
19.5 Subnet-based Bandwidth Management
You can create bandwidth classes based on subnets. The following figure shows LAN
subnets. You could configure one bandwidth class for subnet A and another for subnet B.
Figure 149 Subnet-based Bandwidth Management Example
19.6 Application and Subnet-based Bandwidth Management
You could also create bandwidth classes based on a combination of a subnet and an
application. The following example table shows bandwidth allocations for application specific
traffic from separate LAN subnets.
Table 101 Application and Subnet-based Bandwidth Management Example
TRAFFIC TYPE FROM SUBNET A FROM SUBNET B
VoIP 64 Kbps 64 Kbps
Web 64 Kbps 64 Kbps
