Terminal emulator is a network file transfer application that supports network protocols like SCP, SSH, Telnet etc., to help users configure network devices. Apart from configuring devices, one can also execute commands for both SSH and TELNET. In the older versions of Network Configuration Manager, command execution and configuration was done from the device snapshot page since there was no centralized platform for the devices to access the terminal. But from version 12.3.106, Network Configuration Manager has made it a lot more user-friendly than the older versions as you can directly access the terminal by choosing "Terminal" given under "Tools".
Network Configuration Manager helps to carry out the following functions to make command execution and configuring network devices more reliable:
All the devices present in the Inventory will be listed in the Inventoried. By choosing a suitable protocol such as TELNET/SSH you can start configuring and executing commands for all the devices directly from the Inventoried. You can also search for a particular device by filtering it based on the host name, device type, series and model. This saves a lot of time as you can configure all the devices from a single platform instead of going to the snapshot page of each of these devices to access the terminal.
Back then, to configure MAC and LINUX devices, an external emulator was required and users had to install a third-party client like PuTTY for that purpose. Now, Network Configuration Manager has introduced the "Custom" option to configure MAC and LINUX devices without using an external emulator. The functions provided by "Custom" are:
Add Terminal Device: This helps you to add devices which are not given in the Inventory. The devices which are added will be listed under the "Custom" tab once the credentials and the device type (ex. Windows, Linux, Mac) is provided. You can also provide device visibility such as 'only me'/'Admin' and 'Everyone' thereby making it more reliable.
Delete: Using this option, you can choose one or more than one device which you want to delete. Thus, you can delete devices in bulk saving a lot of time and energy.
Manage Groups: Here, you can add device groups for managing. Thus, devices belonging to one particular groups can be configured in bulk and likewise the commands which are executed will be applied to all the devices belonging to one particular group.
Audit History provides the complete record of all the commands executed on the terminal since Network Configuration Manager records every session of the users and compiles them. When a device configuration is selected, all the commands executed on that particular device will be shown in the sequential order of the command executed. This can be useful for the administrators since he can refer the command history while working on a configuration similar to an existing configuration. Audit History also shows the status of every operation along with the time of execution. Thus, users can carry out all the activities of a terminal from a centralized platform without installing an external emulator.
