Cisco Cisco Web Security Appliance S390 릴리즈 노트

IronPort does not generally support the backward compatibility of configuration files with previous 
major releases. Minor release support is provided. Configuration files from previous versions may work 
with later releases; however, they may require modification to load. Check with IronPort Customer 
Support if you have any questions about configuration file support.

For compatibility between Web Security appliance releases and Security Management appliance 
releases, see the compatibility matrix at: 

This section describes changes in behavior from previous versions of AsyncOS for Web that may affect 
the appliance configuration after you upgrade to the latest version.

The proxystat and rate commands now display the percent of CPU used by the web proxy instead of the 
percent of CPU being used by all processes.

AsyncOS now dynamically adjusts the size of the send buffer for the client-side socket. AsyncOS no 
longer includes the option of the MISCELLANEOUS subcommand of the advancedproxyconfig 
command to configure the size of this buffer.

When opening a support case using the appliance, the severity level is 3. Previously, users were able to 
set the severity level using the appliance, either through the CLI command, supportrequest, or through 
the GUI. To open a support case at a higher severity level, call Customer Support. See 

.
