The SISPM1040-582-LRT supports the DHCP IP Per Port VLAN function. It lets you have an IP address from a
DHCP pool on a switch be statically assigned to a switchport, such that whichever device plugs into the switchport
it will always be assigned that specific IP address. The IP address is configured in the interface config settings.
Note that this is binding an IP address to an interface, not to a MAC address, which is the classic binding
technique found on most switches. (Added at FW VB7.20.0140.
