Volga,

You are trying to use the csv transformation but your data is not comma-separated. You are using semi-colons. I think you are trying to remove the semi-colons with the regex and replace them with commas? I'm not sure what the value of that is, since you could just use commas to begin with. But even if you had to do it that way, you would need the regex to do the substitution *before* trying to access it as a csv. But as I said, easier is to just use commas to begin with.

#### Cfgutils
loadmodule "cfgutils.so"
modparam("cfgutils", "shvset", 
"vip_lan_lst=s:192.168.10.10,192.168.10.11,192.168.10.12")
modparam("cfgutils", "shvset", 
"vip_wan_lst=s:209.234.43.2,209.234.43.3,209.234.43.4")

$var(i) = 0;
while($var(i) < $(shv(vip_lan_lst){csv.count})) {
  xlog("L_INFO", "Testing SHV ~> 
  $(shv(vip_lan_lst){csv.value,$var(i)})");
  $var(i) = $var(i) + 1;
}

    Hello Ben,
    I tried this.
    
    #### Cfgutils
    loadmodule "cfgutils.so"
    modparam("cfgutils", "shvset", 
    "vip_lan_lst=s:192.168.10.10;192.168.10.11;192.168.10.12")
    modparam("cfgutils", "shvset", 
    "vip_wan_lst=s:209.234.43.2;209.234.43.3;209.234.43.4")
    
    
            $avp(arr) = $shv(vip_lan_lst);
            $var(i) = 0;
            while($var(i) < $(avp(arr){csv.count})) {
                    xlog("L_INFO", "Testing SHV ~> 
    $(avp(arr){csv.value,$var(i)}{re.subst,/;/,/})");
                    $var(i) = $var(i) + 1;
            }
    
    but it not working output should print each ip in xlog.
