I couldn't understand your GTM setup though, but from what I understood, you want to mark down the other pool member (2.2.2.2) also, when one of the pool member (1.1.1.1) is marked down. You'll have to use the depends on feature on the GTM to do this. The monitoring will understand that it has a depends on to mark it up.

    Hi Jiakumar_f5,

    Sorry for lacking details in my question...

    So my WIP is mail.example.com. It has two pools (POOL1 and POOL2). POOL1  has LTM1's two VIPs (VIP1 and VIP2) as members. VIP1 and VIP2 are with the same IP address 10.1.1.1 but with different ports (993 for IMAP and 995 for POP3). 

    Right now, we are having issues with the IMAP health monitor on the LTM after the upgrade of the LTM. I have a case open to investigate. The POP3 remains up.  Therefore, the GTM still provides 10.1.1.1 in its DNS response. I want to not give it in the response. 

    Hopefully, this is clear. Thanks!
