Cisco Cisco Web Security Appliance S670 User Guide

The Policy Trace Tool can emulate a client request and then detail how the Web Proxy processes that 
request. It can be used to trace client requests and debug policy processing when troubleshooting Web 
Proxy issues. You can perform a basic trace, or you can enter advanced trace settings and override options. 

The policy trace tool evaluates requests against polices used by the Web Proxy only. These are Access, 
Encrypted HTTPS Management, Routing, Data Security, and Outbound Malware Scanning polices. 

SOCKS and External DLP polices are not evaluated by the policy trace tool.

When you use the policy trace tool, the Web Proxy does not record the requests in the access log or 
reporting database.

Choose System Administration > Policy Trace.

Enter the URL you wish to trace to in the Destination URL field.

(Optional) Enter additional emulation parameters:

Click Find Policy Match.

The policy trace output is displayed in the Results pane.

The client source IP used to make the request.

An IP address in the Client IP Address field.

If an IP address is not specified, AsyncOS 
uses localhost. Also, SGTs (security group 
tags) cannot be fetched and policies based on 
SGTs will not be matched. 

The authentication/identification credentials 
used to make the request.

A user name in the User Name field, and then choose 
Identity Services Engine or an authentication realm 
from the Authentication/Identification drop-down list.

Only enabled option(s) are available. That is, 
authentication options and the ISE option are 
available only if they are both enabled.

For authentication of the user you enter here, the user 
must have already successfully authenticated through 
the Web Security appliance.
