DHCP-Client report hostname to external server

Hi everyone,

I am trying to get the MT DHCP-Client to report the device’s hostname back to an external DHCP server. According to the https://wiki.mikrotik.com/wiki/Manual:IP/DHCP_Client there are three options supported, including hostname. So my questions would be:

1.) is the System Identity the same as the $hostname (or even FQDN), and if not: how can I set it?
2.) how does the DHCP Client / Advanced menu work? You select all DHCP client options you want to report to the server in the upper part of the menu? And you can sort them (why?)?
3.) what would the configuration needed to report the hostname to the DHCP server look like on the MikroTik?

Thanks in advance!

Based on quick test, default hostname sent by DHCP client is taken from system identity. If you want something else without touching identity, you can do:

/ip dhcp-client option
add code=12 name=custom_hostname value="'myrouter'"
/ip dhcp-client
add dhcp-options=custom_hostname,clientid interface=<interface>

Thanks for taking the time to help, much appreciated!

Or more simply…

/ip dhcp-client option set hostname value="'mydevicenicename'"

Notice:
the strig must be delimited between ’ and ’
and is why used " " for represent one string on script and inside is used ’ ’ for represent a DHCP option string value.
