Port Redirect
Looking at situation when application port is down, Client will not take note as it will be redirected to a working port e.g Server 10.10.10.10 listening on port 2022 when port 2022 is down, user...
Hi FAJUMO ,
Why do you bother yourself by redirection.
you can use Priority Group activation feature ( PGA ) within the pool.
For instance : Create a pool contains 2 members ( 10.10.10.10:2022 & 10.10.10.10:2023 ) as long as it's the same service.
so the PoA from my perspective :
1- add the 2 members within same pool with different ports ( no matter )
2- you can assign health monitor for each member independently/separately , this will make your pool to inherit the availability without assigning any health monitor over all the pool.
so here both of members should be available.
3- activate PGA feature with less than 1 , give the first member the higher priority/score to let the traffic to be forwarded to it and give the second member a lower score to let bigip relies on it in case of failures in the first member only.
4- none of your client will observe this change of ports as long as there is a full proxy in between client and servers , which dest address/port should be changed each time this virtual server.
here you're all details about PGA : https://my.f5.com/manage/s/article/K13525153 & https://my.f5.com/manage/s/article/K45041241
I hope this helps you 🙂
Thank you for the help, I appreciate you.
