Logging in through Telnet
Introduction
S3100 series Ethernet switches support Telnet. You can manage and maintain a switch remotely by
Telnetting to the switch.
To log into a switch through Telnet, the corresponding configuration is required on both the switch and
the Telnet terminal.
You can also log into a switch through SSH. SSH is a secure shell added to Telnet. Refer to the SSH
Operation for related information.
