(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 improve system security. The two member devices of an E-Trunk must use the same password.


  1. Run:


    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 plaintext in the configuration file. In this case, other 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 ciphertext.

    To ensure device security, change the password frequently.
