4.2.2 IP Configuration
The Managed Switch is a network device which needs to be assigned an IP address for being identified on the network. Users
have to decide on an IP address for the Managed Switch.
IP address overview
What is an IP address?
Each device (such as a computer) which participates in an IP network needs a unique "address" on the network. It's similar to
having a US mail address so other people have a known way to send you messages. An IP address is a four byte number,
which is usually written in "dot notation" - each of the bytes' decimal value is written as a number, and the numbers are
separated by "dots" (aka periods). An example: 199.25.123.1
How do I get one for this box?
The IP addresses on most modern corporate nets are assigned by an employee called a "Network Administrator", or "Sys.
Admin". This person assigns IP addresses and is responsible for making sure that IP addresses are not duplicated - If this
happens one or both machines with a duplicate address will stop working.
Another possibility is getting your address assigned to you automatically over the net via DHCP protocol. Enable DHCP function,
and reset the machine. If your network is set up for this service, you will get an IP address assigned over the network. If you
don't get an address in about 30 seconds, you probably don't have DHCP set up in your network.
IP Configuration
The IP Configuration includes the IP Address, Subnet Mask and Gateway. The Configured column is used to view or change the
IP configuration. Fill up the IP Address, Subnet Mask and Gateway for the device. The screen in
