1.8 Ethernet Interfaces
How you specify an Ethernet interface depends on the Zyxel Device model.
• For some Zyxel Device models, use gex, x = 1~N, where N equals the highest numbered Ethernet
interface for your Zyxel Device model.
• For other Zyxel Device models use a name such as wan1, wan2, opt, lan1, or dmz.
1.9 Saving Configuration Changes
Use the write command to save the current configuration to the Zyxel Device.
Note: Always save the changes before you log out after each management session. All
unsaved changes will be lost after the system restarts.
1.10 Logging Out
Enter the exit or end command in configure mode to go to privilege mode.
Enter the
exit command in user mode or privilege mode to log out of the CLI.
1.11 Resetting the Zyxel Device
If you cannot access the Zyxel Device by any method, try restarting it by turning the power off and then
on again. If you still cannot access the Zyxel Device by any method or you forget the administrator
password(s), you can reset the Zyxel Device to its factory-default settings. Any configuration files or shell
scripts that you saved on the Zyxel Device should still be available afterwards.
Use the following command to reset the Zyxel Device to its factory-default settings. This overwrites the
settings in the startup-config.conf file with the settings in the system-default.conf file.
Note: This procedure removes the current configuration. Note that there is a space after
apply in the command.
