3.4.4. Network configuration of magicplex8
Figure 9: Network configuration
If you did not choose the “Manual configuration”, these field are enable and pre-filled with the
current information about the selected multiplexer. You can change here the IP address, the
default gateway and the hostname of the current multiplexer. By clicking “Change network
configuration” you will send this new network configuration to the multiplexer
NOTE: The network configuration is independent from the rest of configuration. All other
settings (Port configurations logging, etc) must be set by using the upload configuration function.
3.4.5. Data validation
Data validation is done before trying to change the network configuration. If these controls fail,
then an information message is displayed and nothing happens.
The following controls take place:
- The IP address must be of the form X.X.X.X where X are numbers between 0 and 255.
Additionnally, the first number must be between 1 and 223 (inclusive), and different from
127.
- The netmask must be of the form X.X.X.X where X are numbers between 0 and 255. It
must respect the constraints of a netmask (i.e. as a binary representation, it must be a
continuous sequence of 1 followed by a continuous sequence of 0). 0.0.0.0 and
255.255.255.255 are forbidden.
- The combination of the IP address and the netmask must make sense: the "host" part of
the IP address (not masked by the netmask) can not be 0.
- The default gateway can be empty (no default gateway will be used), but if not, it must be
of the form X.X.X.X where X are numbers between 0 and 255. The first number can not
be 0.
- The hostname can be any combination of small unaccentuated letters (a-z), capital
unaccentuated letters (AZ), numbers (0-9), dashes (-), underscores (_) and points (.). It
must contain between 1 and 32 characters (inclusive). This means for example that it can
not contain any space.
