Feature Overview
The Dynamic Feedback Protocol (DFP) enables a DFP agent in a local load-balancing environment to
collect status information from one or more real host servers, convert the information to relative weights,
and report the weights to a DFP manager, such as an IOS Server Load Balancing (SLB) device. The DFP
manager factors in the weights when load balancing the real servers. DFP also supports global
load-balancing environments, with IOS SLB reporting weights to DistributedDirector. For more
information about DFP, see the IOS Server Load Balancing feature module.

Prior to 12.1(8a)E, the DFP agent was implemented only in IOS SLB. The new DFP agent subsystem
feature enables client subsystems other than IOS SLB to act as DFP agents. However, currently IOS SLB
is the only supported subsystem. You can use multiple DFP agents from different client subsystems at
the same time.
