Script to find virtual servers with connection mirroring enabled

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.

    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?
