Cisco Cisco Email Security Appliance C160

The documentation for the Cisco IronPort Email Security appliance includes the 
following books:

Cisco IronPort AsyncOS for Email Daily Management Guide. This guide 
provides instructions for performing common, everyday tasks that system 
administrators use to manage and monitor the IronPort appliance, such as 
viewing email traffic using the Email Security Monitor, tracking email 
messages, managing system quarantines, and troubleshooting the appliance. 
It also provides reference information for features that system administrators 
interact with on a regular basis, including Email Security Monitor pages, 
AsyncOS logs, CLI support commands, and quarantines.

If you rename an encryption profile that is being used by a DLP policy, AsyncOS does 
not automatically update the DLP policy with the updated encryption profile name. 
AsyncOS will bounce messages that match the DLP profile.

When creating a cluster of appliances running AsyncOS 7.3, the CLI displays error 
messages stating that the 

/etc/ssh/ssh_host_key.pub

 and 

/etc/ssh/ssh_host_dsa_key.pub

 system host keys cannot be opened. These host 

keys listed do not exist on the appliance. Cisco IronPort advises you to ignore these 
error messages.

The “reconnect” link in the GUI does not reconnect machines that were disconnected 
from a cluster unless the machines were disconnected from the cluster individually. 
Workaround: Use the 

clusterconfig -> reconnect

 command in the CLI to 

reconnect the machines.
