2.3. 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 suppo
rt 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.
