Ensure 'Master Key Passphrase' is set

中レベル 1自動cisco-asa

説明

Defines the master key passphrase used to encrypt the application secret-keys contained in the configuration file for software releases from 8.3(1) and above. For ASA software releases from 8.3 and below, the VPN preshared keys, Tacacs+/Radius shared keys or Routing protocols authentication passwords are encrypted in the running-configuration once generated. 'password encryption aes' is only accepted once a master key passphrase is set. Audited against the output of 'show running-config' (run 'terminal pager 0' first; 'more system:running-config' also works and shows unmasked secrets).
