(Optional) Setting the Password for Encrypting Packets

(Optional) Setting the Password for Encrypting Packets


You can set a password for encrypting E-Trunk packets transmitted over an E-Trunk link to enhance system security. The two member devices of an E-Trunk must use the same password.

You can set a password in plain text or cipher text. The following describe the two passwords types:
  • The plain text password is displayed in plain text in the configuration file.

  • The cipher text password is displayed as unidentifiable characters in the configuration file.


  1. Run system-view

    The system view is displayed.

  2. Run e-trunk e-trunk-id

    The E-Trunk view is displayed.

  3. Run security-key { simple simple-key | cipher cipher-key }

    The password for encrypting packets is configured.

    If simple is specified, the password is saved in plain text in the configuration file. In this case, lower-level users can obtain the password by querying the configuration file, which poses a security risk. You are advised to specify cipher so that the password is saved in cipher text.

    To ensure device security, change the password periodically.
