To do… Use the command… Remarks
Configure the device to log in to a
Telnet server as a Telnet client
telnet remote-host [ service-port ]
[ source { interface interface-type
interface-number | ip ip-address } ]
Required
Use either command
Available in user view
telnet ipv6 remote-host [ -i
interface-type interface-number ]
[ port-number ]
Specify the source IPv4 address or
source interface for sending Telnet
packets
telnet client source { interface
interface-type interface-number | ip
ip-address }
Optional
By, no source IPv4 address or
source interface is specified. The
source IPv4 address is selected by

Logging in through SSH
Introduction
Secure Shell (SSH) offers an approach to log into a remote device securely. By providing encryption and
strong authentication, it protects devices against attacks such as IP spoofing and plain text password
interception. The device supports SSH, and you can log in to the device through SSH to remotely manage
and maintain the device, as shown in Figure 22.

uirements
SSH server
Configure the IP address of the management Ethernet interface, and make
sure the SSH server and client can reach each other.( By default, the IP
address of the management Ethernet interface is 192.168.0.1/24.)
Configure the authentication mode and other settings.
SSH client
If the host operates as an SSH client, run the SSH client program on the host.
Obtain the IP address of the management Ethernet interface of the device
By default, the device is enabled with the SSH server and client functions.
• On a device that serves as the SSH client, you can log in to an SSH server to perform operations on
the server.
• On a device that serves as the SSH server, you can configure the authentication mode and user level
for SSH users. By default, password authentication is adopted for SSH login, but no login password
is configured, so you cannot log in to the device through SSH by default. Before you can log in to
the device through SSH, you need to log in to the device through the console port and configure the
authentication mode, user level, and common settings.
