i Call script for shutting down F5 LTM interface

Hi Experts

How will I ensure that multiple conditions trigger port shutdown on the F5 VIPRION, running 11.5.1? For example, I am tracking a pool IP member (say 8.8.8.8 on the Internet) and based on that tracking I have to shutdown four ingress ports, say 1/1.1, 1/1.3, 1/1.5, 1/1.9.

We have to verify if the above interfaces are up, then only the script should shut them down.

IP 8.8.8.8 is reachable via another set of interfaces, say 1/1.6, 1/1.10, 1/1.14.

I am not able to combine both these conditions in the i-call statement.

Will F5 TAC support such customizations on the LTM product line?

Sample given below. However, this does not check port status before shutting them down.

sys icall script /Common/vsuf_down {
app-service none
definition {
     This script is triggered via alertd and will enable ingress links if next hop IP is UP

    set cgnat "/Common/CGNAT-Instance"

     IP pool ping status to 8.8.8.8
    set dev_objs [tmsh::get_status /ltm pool $cgnat]
    foreach dev_obj $dev_objs {
    set STATUS_1 [tmsh::get_field_value $dev_obj "status.availability-state"]
}

    ----------------------------------------------------
     If IP is DOWN, disable ingress trunk
    ----------------------------------------------------
       tmsh::log " $STATUS_1"
    if {$STATUS_1 == "available"}{
       tmsh::log "IP 8.8.8.8 is UP. DISABLING ingress TRUNK"
       tmsh::modify /net interface 1/1.1 disabled
       tmsh::modify /net interface 1/1.5 disabled
    }
}
