Cisco Cisco Email Security Appliance C160 Mode D'Emploi

Ensure that you have the configuration file for the version you wish to revert to. Configuration files are 
not backwards-compatible. To do this, you can email the file to yourself or FTP the file. For information, 
see 

.. 

Save a backup copy of the current configuration of your appliance (with passphrases unmasked) on 
another machine.

This is not the configuration file you will load after reverting.

If you use the Safelist/Blocklist feature, export the Safelist/Blocklist database to another machine.

Wait for the mail queue to empty.

Log into the CLI of the appliance you want to revert.

When you run the 

revert

 command, several warning prompts are issued. After these warning prompts 

are accepted, the revert action takes place immediately. Therefore, do not begin the reversion process 
until after you have completed the pre-reversion steps. 

From the CLI, Issue the 

revert

 command.

The reversion process is time-consuming. It may take fifteen to twenty minutes before reversion 
is complete and console access to the appliance is available again.

Wait for the appliance to reboot twice. 

After the machine reboots twice, use the serial console to configure an interface with an accessible IP 
address using the 

interfaceconfig

 command. 

Enable FTP or HTTP on one of the configured interfaces.

Either FTP the XML configuration file you created, or paste it into the GUI interface.

Load the XML configuration file of the version you are reverting to.

If you use the Safelist/Blocklist feature, import and restore the Safelist/Blocklist database.

Commit your changes.

The reverted appliance should now run using the selected AsyncOS version. 

You can configure the envelope sender for mail generated by AsyncOS for the following circumstances:
