Nortel Switched Firewall 2.3.3 User’s Guide and Command Reference
260
The Command Line Interface
213455-L, October 2005
Multiple administration sessions
It is possible to have more than one CLI or BBI administrator session open at the same time.
Although each concurrent administrator session is independent, when configuration changes
are saved to the Single Software Image (SSI) that is shared by the firewall, the saved changes
affect all users. However, if multiple CLI or BBI administrators apply changes to the same set
of parameters concurrently, the latest applied changes take precedence.
Global commands
Some basic commands are recognized throughout the entire menu hierarchy. These commands
are useful for obtaining online help, navigating through menus, and for applying and saving
configuration changes:
