Basic VIPs


There are three main players when working with the F5's.  The Virtual Server is the VIP or external IP address that traffic goes to.  It in turn points to a Pool (or multiple pools) that in turn has multiple servers or Members.

Create A Pool: 

The pool is simply a collection of real servers, how to monitor those servers, and the method to spray traffic over those servers.  

To create a new pool, under 
Main :: Local Traffic :: Virtual Servers :: Pools :: Pool List 
Select the "+" to create a new pool.  

Then in the new pool window, fill in the following fields: 
  1. Name: Enter a name for the pool
  2. Description: Add some description so you can remember what this is over any of the other pools
  3. LB Method: There are a bunch of different methods for balancing traffic.  For now, simply enter Round Robin.  
  4. New Members: For each real server, provide a description and either its IP or DNS name, 
  5. Add: Select the add button to save each defined New Member
  6. Finished: When you are done entering in all the New Members, enter Finished.  

Create a Virtual Server

A Virtual Server is the front end VIP that external traffic will go to.  The VS handles SSL certs, protocol conversion (ie: https to http), compression and any scripting like iRules.  

To create a new server, under 
    Main :: Local Traffic :: Virtual Servers :: Virtual Servers List
select the "+" icon to create a new VS

In the New Virtual Server window, enter in the following fields
  1. Name: Name of the Virtual Server
  2. Description: Description to remind you what this is used for
  3. Type: Standard.  Should be a normal web VS.  The other types are noted in sol14163.  
  4. Destination: The IP address of the VIP that external traffic should point to
  5. Service Port: The port that should be listening on the Destination IP.  (ie: 80=http, 443=https)
  6. HTTP Profile: Select HTTP Profile for basic web traffic 
  7. SNAT Pool: For internal routing.  Enable this if you want traffic to the servers to be sourced from the F5.  See more on this here. 
  8. Default Pool: Select the pool name you created in the "Create a Pool" section above
  9. Default Persistence Profile: Select if you want to enable stickiness.  See more here. 
  10. Finished: Select the finished button to save your changes.
