You can use the CLI interface to configure, provision, and monitor Passport 4400 units.
You can access the CLI locally by using an asynchronous terminal device (or PC using terminal emulation software) connected to the serial management port on the Passport 4400 base module. You can also access the CLI remotely using Telnet. The workstation using Telnet must have IP connectivity or be directly connected to the Ethernet port on the Passport 4400. Only one CLI session can be active at a time on a Passport 4400 unit.
