Afaik the /24 is correct for the local network, although I don't know
what it means. Seems like this is called prefix length in the switch.
The netmask according to the switch settings is 255.255.255.0.

It definitely worked in rc.conf with 255.255.0.0 as netmask and
aforementioned gateway, some links that can shed light on
this stuff, especially the strange /24, would be welcome.
