Why don't you use switch management config that is described under type 3 in
the link you posted? I always use it since it's simple and I can use it in
networks in which my clients don't want to add new ip network/host in the
routing topology just for switch management purposes, so the switch is
basically a new ip host in the existing ip network/subnet.
With this type of network management ip int you'll get on simplicity, but of
course recommendation is to use separate broadcast domain (for security and
availability reasons) for your net management purposes.
