is defined for the application type.

Step 7
Submit and commit your changes.
Controlling Instant Messaging Traffic
You can use the AVC engine to apply control settings to some instant messenger (IM) traffic that runs 
on top of HTTP. You can block or monitor the IM traffic, and depending on the IM service, you can block 
particular activities (also known as application behaviors) in an IM session. For example, you can allow 
an IM session with a particular IM service provider, but block file transfers within that session.
The AVC engine does not control native IM traffic.
You control IM traffic by configuring Instant Messenger application settings on the Applications 
Visibility and Control page of Access Policies.
To control IM traffic:
Step 1
Navigate to the Web Security Manager > Access Policies page.
Step 2
Click the link in the policies table under the Applications column for the policy group you want to edit. 
The Applications Visibility and Control page appears.
Step 3
Expand the Instant Messaging application type.
Step 4
Click the link next to the IM application you want to configure.
Click to expand the Instant Messaging application type.
