this is so shameful for me, i hace experience in some programming languages, routers included, and when i post some question it’s because i’ve tried everything, last night i try a lot of times this
:foreach iface in=[/ip dhcp-client find comment~"balance" && status="bound"] do={
:set ifname ([/ip dhcp-client get $iface interface]);
:log info $ifname;
};
but doesn’t work, but now it works normal, maybe i was so tired and have some typo error, thanks a lot.
