URL Filtering 
Enhancement 

You can now configure the appliance not to replace the URLs within 
HREF tags with secure proxy URLs. However, if an end user clicks these 
URLs, the end user will be redirected to the secure proxy. 

You can configure this option using the 

websecurityadvancedconfig

 

command in CLI. See CLI Reference Guide for AsyncOS for Cisco Email 
Security Appliances.

Option to Send Potentially 
Malicious File Types for 
File Analysis

Cisco periodically checks for potentially malicious file types to prevent 
zero day threats. If new threats are identified, details of such file types are 
sent to your appliance through updater servers. If you enable this 
functionality, your appliance will send such file types for analysis in 
addition to the file types you have selected.

Select the Other potentially malicious file types option on the File 
Reputation and Analysis Settings page (Security Services > File 
Reputation and Analysis > Edit Global Settings > File Analysis 
section) to enable this functionality.

For information about the new file types that are analyzed, see File 
Criteria for Advanced Malware Protection Services for Cisco Content 
Security Products, available from

LDAP 

LDAP queries that return certain error codes such as Unavailable, Busy, or

server failed.

Option to accept or reject 
ARP replies with a 
multicast address

While configuring ethernet media settings using the
