Hi All, I am working on to turn off connection mirroring on all the legacy VIPs which are causing application performance degradation. Is there a way to automate and discover virtual server with connection mirroring enabled via script? and also disable automatically? Thanks

Hello Macaron.You need to perform bash engineering. Some examples:tmsh list ltm virtual mirror | grep -B1 enabled tmsh list ltm virtual mirror | grep -B1 enabled | grep ltm | awk '{print $3}' tmsh list ltm virtual one-line all-properties | grep "mirror enabled" | awk '{print $3}' tmsh -q -c "cd / ; list ltm recursive one-line all-properties" | grep "mirror enabled" | awk '{print $3}' # This last one to capture VS located in different partitions.Regarding the 1000 records, you should not have any problem, but it's better to execute it when CPU/RAM consumption in management plane is low.Regards,Dario.

Hello Macaron.

You can use some of these commands
## Check Mirroring Enabled tmsh show sys connection type mirror tmsh show sys ha-mirror

  The first command returned 1200 plus connection records for 37 VIPs in total on F5. I need to identify VIPs which has connection mirroring enabled. Is there any command for that?

    Hello Macaron.
    You can check what SNAT IPs are mirroring with the next command:
    tmsh list ltm snat mirror
    The same for those VS that are mirroring their connections:
    tmsh list ltm virtual mirror
    And finally, the same for those VS that are mirroring their persistence records:
    tmsh list ltm virtual mirror persist { $(tmsh list ltm persistence one-line all-properties | grep "mirror enabled" | awk '{print$4}') }
    For disabling mirroring, you just need to modify the 'mirror' option as expected.
