Duplicate Unit IDs

Hello,

 

 

I hve a redundant pair that currently has 2 boxes with the same Unit ID. Will this affect the syncingcapability or any little errors? We do notice that the standby box always shows its monitors going down in he logs.

 

 

Any ideas or direction?

 

 

Thank you

    Hi,

     

     

    The unit ID is only used in an active - active pair for setting which unit should own which objects. I don't think it would have anything to do with monitoring failures. If you're using an active - standby configuration the unit ID shouldn't have any impact on anything.

     

     

    Here is a page with some tips on troubleshooting monitor failures:

    Sure. It's changed in 9.4.2 so there are two methods.

    From SOL4802:

     

    https://support.f5.com/kb/en-us/solutions/public/4000/800/sol4802.html

     

     

    For BIG-IP versions 9.4.2 and later:

     

     

    bigpipe system hostname

     

     

    Replace with the fully qualified hostname for the BIG-IP system.

     

     

    For example:

     

     

    bigpipe system hostname askbig9n1.askf5.com

     

     

    For BIG-IP versions 9.0 through 9.4.1:

     

     

    bigpipe db HostName

     

     

    Replace with the fully qualified hostname for the BIG-IP system.

     

     

    For example:

     

     

    bigpipe db HostName askbig9n1.askf5.com
