Management Access Modes
COMMANDO SoldierOS IP Base switches Management is made easy via a web-based Graphical User Interface (WEBUI) access via HTTP/HTTPS or industry-standard Command Line Interface (CLI) via Console/Telnet with administration traffic protected via , SNMP v1/v2C/v3, SSH v1/v2, RMON v1/v2 which enables the switch to be polled for valuable status information and allows it to send traps when abnormal events occur.
Simplified Configuration and Management
Zero-Touch Provisioning (ZTP) simplifies installation of the switch. Easy to manage via Console/web-Based Management (WEBUI)/Telnet/SSH/ HTTPS.
Remote Manageability
Remote management is the process that allows the administrators to take full control of all operations using a remote. This remote management via WEBUI / Telnet/ SSH/ HTTPS will reduce time and money spent on management and maintenance and physical presence of Network Engineer.
Management by CLI- Console, Telnet (RFC854) up to 3 sessions
Management by WebUI- HTTP, HTTPS for management Based on Remote Configuration and maintenance Using Telnet.
In this CLI guide we will understand Management by Command Line Interface(CLI) through console port, telnet management mode.
Accessing the Switch via console port
How to Login COMMANDO Series IE2000 via console port?
The console interface is used by connecting the Switch to an VT100–compatible terminal or a computer running an ordinary terminal emulator program (e.g., the HyperTerminal program included with the Windows operating system) using an RS–232C serial cable. Your terminal parameters will need to be set to:
• VT–100 compatible
• 115200 baud
• 8 data bits
• No parity
• One stop bit
• No flow control
Users may also access the same functions over a Telnet interface. Once you have set an IP address for your Switch, you can use a Telnet program (in VT–100 compatible terminal mode) to access and control the Switch. All of the screens are identical, whether accessed from the console port or from a Telnet interface.
Step 1 :Connect the Switch console port with PC/Laptop via console cable.
Fig-1. Connection of console port with PC/Laptop via console cable.
Step 2 ：The communication parameters configuration of the Putty Terminal with console is shown below Baud rate (Speed):115200
Fig-2. Putty configuration in PC for console port access
Step 3 : Click on “Open”. You will get following window.
With the console port properly connected to a management computer, the following screen should be visible.
