Cisco Cisco Email Security Appliance C380 Release Notes

When you begin upgrading your C160 to AsyncOS 7.1.3, the appliance first 
checks for the Cisco IronPort Hard Drive Firmware Upgrade. If the firmware 
upgrade is pending, appliance prompts you to complete it prior to upgrading your 
C160 to AsyncOS 7.1.3. This firmware upgrade fixes a bug in the driver controller 
code on the hard drives used on C160 appliances that sometimes caused requests 
to timeout in certain conditions, which resulted in errors or the drive going offline. 
[Defect ID: 73406]

See the Cisco IronPort Hard Driver Firmware Upgrade for C160, S160, and 
M160 Appliances Release Notes on the Cisco.com support site for more 
information.

IronPort Security Management appliances running AsyncOS 6.7.3 or earlier do 
not support reporting data for the DLP and Marketing Mail features in AsyncOS 
7.0 or later. If your IronPort Email Security appliance uses centralized reporting, 
the Security Management appliance discards the reporting data for those features. 
If the Security Management appliance is running AsyncOS 6.7.0 or 6.7.3, it sends 
an alert once each time the reporting service begins, such as on a reboot, stating 
that the reporting service is receiving data that it cannot process.

Your Security Management appliance must be running AsyncOS 6.7.6 or later in 
order to use centralized reporting for the DLP and Marketing Mail features.

SNMP does not start when you boot the appliance after upgrading to AsyncOS 
7.1.1. Use 

snmpconfig -> setup

 and then 

commit 

to enable it.

For DKIM Authentication, IronPort currently supports version 8 of the Draft 
Specification of ‘Authentication-Results:’ header.
