DHCP-server lease-time

In Webfig Terminal (RouterOS v6.47.9), when I attempt to set a lease time:

/ip dhcp-server set lease-time 0s

an error returns:

expected end of command (line 1 column 32)

The problem has nothing to do with

0s

(indefinite lease); error is the same regardless of argument, regardless of number, with or without “s”. If I terminate the line with no argument, it returns "

no such item

". What is wrong?

You have to specify the dhcp server instance/config.

Thanks, but can you point me toward info on that? I have found nothing in the wiki or new documentation on it, and am getting no leads from the command line help.

/ip dhcp-server add address-pool=dhcp_pool0 disabled=no interface=bridge1 name=dhcp1 lease-time=0s

It’s in the docs but the option isn’t on many of the examples. When in doubt use tab completion. I’m not sure if it’s available in webfig since I don’t use it.
