Binding to IP Address
The IP address of a network device is assigned by either the system administrator
or through a DHCP server. Binding a virtual port to an IP address will force that
virtual port to attempt a connection to any device with that particular IP address
only. Binding to an IP address provides dynamic connections. Device IP addresses
can be reassigned at any time to cause client PCs to form new connections
without being reconfigured.
Note: When no bindings have been stipulated, a virtual port is implicitly bound
to an IP address because such an address is required to make a connection.
However, IP Extender Manager will attempt to make intelligent corrections to
unbound virtual ports if it detects any problems. IP bound ports will not be
checked by the IP Extender Manager.
Binding to more than one parameter
Usually, one degree of binding is sufficient for an individual virtual port to
achieve the goals of robust communication and flexibility. It is also possible
to bind a virtual port to more than one parameter. Doing so requires careful
consideration of the implications of maintaining connectivity. If multiple
bindings are selected for one port, all individual binding parameters must
match for a connection to be made. For example, enabling both IP address and
MAC address bindings for a virtual port would cause that virtual port to find a
particular physical device by MAC address, but make a connection only if the
device’s IP address also matched the binding setting.
Virtual port COM number assignment
By default, an NETRS232 Link virtual serial port is assigned to the next available COM
number when it is activated. This COM number assignment can be reassigned to any
unused COM number from 1 to 256. For many applications, an alphanumeric name can
be used instead of a COM number.
