iCall for working as if LLCF (4EA Interface)

Ok, just to make sure this worked, I modified for my local vmware fusion environment (updated above to add the correct enabled/disabled keywords) and it works just fine.

user_alert.conf as is on my system:

alert interface_1_1_down "Link: 1.1 is DOWN" {
    exec command="tmsh generate sys icall event interface_manager context { { name action value disabled } { name interface value 1.1 } }"
}
alert interface_1_3_down "Link: 1.3 is DOWN" {
    exec command="tmsh generate sys icall event interface_manager context { { name action value disabled } { name interface value 1.3 } }"
}
alert interface_1_1_up "Link: 1.1 is UP" {
    exec command="tmsh generate sys icall event interface_manager context { { name action value enabled } { name interface value 1.1 } }"
}
alert interface_1_3_up "Link: 1.3 is UP" {
    exec command="tmsh generate sys icall event interface_manager context { { name action value enabled } { name interface value 1.3 } }"
}

 bigip_script.conf appropriate objects as is on my system:

sys icall script interface_manager {
    app-service none
    definition {
        foreach var { action interface } {
            set $var $EVENT::context($var)
        }
        switch ${interface} {
            "1.1" {
                tmsh::modify /net interface 1.3 ${action}
            }
            "1.3" {
                tmsh::modify /net interface 1.1 ${action}
            }
        }
    }
    description none
    events none
}
sys icall handler triggered interface_manager {
    script interface_manager
    subscriptions {
        interface_manager {
            event-name interface_manager
        }
    }
}
