II-3. Preparation for Telnet/SSH Interface
Both telnet and SSH (Secure Shell) are network protocols that provide a text-based command line interface (CLI)
for in-band system management. However, only SSH provides a secure channel over an un-secured network,
where all transmitted data are encrypted.
This switch support both telnet and SSH management CLI. In order to access the switch’s CLI via telnet or SSH,
both your PC and the switch must be in the same network. Before using the switch’s telnet/SSH management
CLI, please set your PC’s network environment according to the previous chapter (2.2. Preparation for Web
Interface).
Telnet interface can be accessed via Microsoft “CMD” command. However, SSH interface can only be
accessed via dedicated SSH terminal simulator. The following section will use PuTTY as an example to
demonstrate how to connect to the switch’s SSH CLI, since both telnet and SSH uses the same way
(though using different terminal simulator software) to access in-band management CLI.
Access SSH via Putty:
A “PuTTY Configuration” window will pop up after you run PuTTY.
1. Input the IP address of the switch in the “Host Name (or IP address)” field. The default IP address
of the switch if 192.168.2.1.
2. Choose “SSH” on the “Connection type” section, then press “Enter”.
