You can view the history of unit password changes done through Security Center, using the Unit Assistant role. You can use
this information to diagnose problems that might have occurred during a password
change.
What you should know
-
You
need the View/export unit passwords privilege to perform this task.
-
Password history details include when a unit's password was
changed, what the previous password was, and what the password was changed to. You can use
this information to resolve connectivity issues by retrying old passwords.
Procedure
-
From the Config Tool homepage, open the Video task and click the
Roles and units view.
-
Select the video unit you want and click the Properties
tab.
-
In the Authentication section, select Unit password
history.
The Unit password history dialog box opens showing the
details of the previous password change attempts including the date, the previous
password, and the new password.
-
Click Recover password to recover all previous passwords.
NOTE: The Recover password button is only available if there is a
connection issue between the unit and Security Center.
If the Unit Assistant role is able to communicate with a password in the
history, Security Center uses this password and
reconnects the unit.
