To Telnet to another device from the local switch, follow these steps:
1.
Set up a configuration environment as shown in
. If the two switches are not in the same
LAN, make sure the two switches can reach each other.
Figure 10 Telnetting from the switch (Telnet client) to another device (Telnet server)
2.
Configure the Telnet server:
a.
Enable the Telnet server.
b.
Configure the authentication mode on the Telnet server as needed.
3.
Log in to the switch that operates as the Telnet client.
4.

Optional.
By default, no source IPv4
address or source interface for

Logging in through SSH
SSH offers a secure method for remote login. By providing encryption and strong authentication, it
protects devices against attacks such as IP spoofing and plain text password interception. You can use an
SSH client to log in to the switch working as an SSH server for remote management, or use the device as
an SSH client to log in to an SSH server, as shown in
