BigIP Question

Forgive my ignorance as I am pretty unfamiliar with the technoligies available in the BigIP appliances.

 

 

Version: BigIP 4.5.14

 

 

Given: Two servers sitting in a pool behind a BigIP listing on a specific UDP port.

 

 

Can I configure the BigIP to send all traffic to only one of the two servers until it determines that that server is down (icmp monitor), and then send all traffic to the second server?

 

 

Thanks in advance for your help, it is GREATLY appreciated.

 

 

Bob

    Hi Bob,

     

     

    Sure, you can do this by using priority groups in a pool. Set the member you want to receive all the connections to a higher priority and it will receive all the requests. Set the minimum active members to 1. If the monitor marks that member down, the other member will receive all the requests. When the first member comes back up, it will again receive all of the connections.

     

     

    This is described in SOL2422 (Click here), the help page for pool configuration page in the admin GUI, or the BIG-IP Reference Guide for your version.

     

     

    Also, in addition to pinging the member IP, you might want to add a port-specific UDP monitor to make sure the service is up.
