Special note for AES ciphers:
The Legrand PDU device's SSL/TLS-based protocols, including SMTP over StartTLS, support AES 128- and
256-bit ciphers. The exact cipher to use is negotiated between Legrand PDU and the client (such as a web
browser), which is impacted by the cipher priority of Legrand PDU and the client's cipher availability/settings.
Tip: To force Legrand PDU to use a specific AES cipher, refer to your client's user documentation for
information on configuring AES settings.
Changing SSH Settings
You can enable or disable the SSH access to the command line interface, change the TCP port, or set a
password or public key for login over the SSH connection.
To change SSH settings:
1. Choose Device Settings > Network Services > SSH.
2. To enable or disable the SSH access, select or deselect the checkbox.
3. To use a different port, type a port number.
