Introduction
S5100-SI/EI series Ethernet switches support Telnet. You can manage and maintain a switch
remotely by Telnetting to the switch.
To log in to a switch through Telnet, the corresponding configuration is required on both the switch and
the Telnet terminal.
You can also log in to a switch through SSH. SSH is a secure shell added to Telnet. Refer to the
SSH Operation for related information.
