2. Specify the source IPv4
address or source interface
for outgoing Telnet packets.

Logging in through SSH
SSH offers a secure approach to 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 device operating as an SSH server for remote management, as shown in Figure
35. Y
ou can also use the device as an SSH client to log in to an SSH server.

Table 7 shows the SSH server and client configuration required for a successful SSH login.
