9.10 IP Settings for Diagnostics (uC DIAG)

922-DSLH cards include an IP validation feature in the Telnet interface. This feature checks for a valid IP and
subnet combination. If an invalid IP Address is entered using the "set ip" command, the Telnet interface will
show the user the valid range of IP addresses within the current subnet. Additionally, subnet validation will
ensure that the user is providing a valid subnet when using the "set subnet" command. Examples of an invalid
IP entry, a valid IP entry and an invalid subnet entry can be seen in the figures below.
IP validation also occurs during the startup procedure. If on startup an invalid IP address or subnet is read
from the EEPROM, these parameters will be set to the factory defaults.
