LXI Ports, Protocols, and Services
LXI conformant devices have a standard set of Ports, Protocols, and Services for
LAN operation, but there are also LXI Device-specific Ports, Protocols, and Services.
LXI Extended features are optional, and the Home page of the LXI Device lists these
extended features, if implemented.
