26 ESR Series Routers Operation Manual
4 MANAGEMENT INTERFACES
You may use various management interfaces in order to control and monitor the device.
To access the device, you may use network connection via Telnet or SSH as well as direct
connection via RS-232 compliant console port. For Telnet, SSH or console port connections, the command
line interface is used for device management.
Factory settings contain trusted zone description and IP address for device management
access—192.168.1.1/24.
Trusted zone includes the following interfaces:
For ESR-100: GigabitEthernet 1/0/2-4;
For ESR-200: GigabitEthernet 1/0/2-8;
For ESR-1000: GigabitEthernet 1/0/2-24;
For ESR-1200: GigabitEthernet 1/0/2-16, TengigabitEthernet 1/0/3-8
By default, the user 'admin' with the password 'password' is defined in factory settings.
For each management interface provided, there are unified configuration operating principles.
When modifying and applying the configuration, you should follow the specific sequence described herein
that is intended to protect the device from misconfiguration.
4.1 Command line interface (CLI)
Command Line Interface (CLI) allows to perform the device management and monitor its operation
and status. You will require the PC application supporting Telnet or SSH protocol operation or direct
connection via the console port (e.g. HyperTerminal).
Command line interface enables user authorization and restricts access to commands depending on
their access level, provided by the administrator.
You can create as many users as you like, access rights will be assigned individually to each user.
To ensure command line interface security, all commands are divided into 2 categories—privileged
and unprivileged. Privileged commands basically include configuration commands. Unprivileged
commands include monitoring commands.
The system allows multiple users to connect to the device simultaneously.
