Introduction to PROFILES in F5?

--> Profiles are the collection of settings that define traffic behavior or traffic policy applied on a virtual server.

--> In simple terms, a profile is an object in BIG IP LTM that controls the behavior of a particular type of network traffic such as HTTP.

--> By using profiles in F5 LTM, we can perform following tasks,

1) Change the traffic behavior of some types of network traffic.

2) Improves performance and throughput in the network.

3) We can implement persistence and SSL offloading by using profiles.

--> It is possible to apply multiple profiles to the single virtual server.

--> By default, BIG IP LTM comes with some set of profiles which we can apply to virtual servers.

--> This profiles are called default profiles.

--> It is also possible to create custom profiles in BIG IP LTM.

--> A profile can be associated to a virtual server at the time of creation of virtual server or later on.

--> Each and every profile working on a given layer of the OSI model is dependent upon the lower layers.

--> In simple terms, if a profile is working on Application layer is dependent on the transport layer.

--> Every virtual server have a layer 4 profile assigned to it.

--> It is not possible to apply both TCP and UDP profiles to a virtual server as well as FTP and HTTP profile also.
