Adding or Changing the Master Passphrase
This section describes how to add or change the master passphrase.
Prerequisites
• If failover is enabled but no failover shared key is set, an error message appears if you change the
master passphrase, informing you that you must enter a failover shared key to protect the master
passphrase changes from being sent as plain text.
In the Configuration > Device Management > High Availability > Failover pane, enter any character
in the Shared Key field or 32 hexadecimal numbers (0-9A-Fa-f) if a failover hexadecimal key is
selected, except a backspace
. Then click Apply.
To add or change the master passphrase, perform the following steps:
Step 1 In single context mode, choose Configuration > Device Management > Advanced > Master
Passphrase.
In multiple context mode, choose Configuration > Device Management > Device Administration >
Master Passphrase.
Step 2 Check the Advanced Encryption Standard (AES) password encryption check box.
If no master passphrase is in effect, a warning message appears when you click Apply. You can click
OK or Cancel to continue.
Model License Requirement
All models Base License.
