SNMP-based Management 

 

Management Options 

To configure, manage, and monitor the software features on the Switch, users can connect to the Command Line 

Interface (CLI), Web User Interface (Web UI), or through the means of third-party SNMP software. 
 

Command Line Interface (CLI) 

The CLI provides access to all of the software features available on the Switch. These features can be enabled, 

configured, disabled, or monitored by simply entering the appropriate command after the CLI prompt and pressing the 

Enter key. The Console port offers an Out-Of-Band (OOB) connection to the CLI and the LAN ports offers an in-band 

connection to the CLI using Telnet or SSH. 
 

 

NOTE:

 For more information about the CLI, refer to the 

DGS-1520 Series CLI Reference Guide

 

Connecting to the Console Port 

The Console port is used to connect to the CLI of the Switch. Connect the DB9 connector of the console cable 

(included in the packaging) to the Serial (COM) port of the computer. Connect the RJ45 connector of the console 

cable to the Console port on the Switch. 
 
To access the CLI through the Console port, 

Terminal Emulation Software

 must be used like 

PuTTY

 or 

Tera Term

The Switch uses a connection of 

115200 

bits per second with 

no flow control

 enabled. 

 

Figure 5-1 Console Connection Settings 

 
After the boot sequence completed, the CLI login screen is displayed. 
 

 

NOTE:

 The default username and password for the CLI and Web UI is 

admin
