Cisco Cisco Web Security Appliance S170 사용자 가이드

The AVC engine allows administrators to control the amount of bandwidth used for particular 
application types. Not all application types support bandwidth controls.

You can define the following bandwidth limits:

Overall bandwidth limit. Define an overall limit for all users on the network for the supported 
application types. The overall bandwidth limit affects the traffic between the Web Security appliance 
and web servers. It does not limit traffic served from the web cache. You might want to define an 
overall bandwidth limit to restrict the amount of network traffic used for high traffic sites, such as 
streaming media sites. For more information, see 

.

User bandwidth limit. Define a limit for particular users on the network per application type. User 
bandwidth limits traffic from web servers as well as traffic served from the web cache. You might 
want to define user bandwidth limits to restrict the amount of traffic consumed by heavy usage users 
to enforce acceptable use policies. For more information, see 

.

When both the overall limit and user limit applies to a transaction, the most restrictive option applies.

You can define bandwidth limits for particular URL categories by defining an Identity group for a URL 
category and using it in an Access Policy that restricts the bandwidth.

Defining bandwidth limits only throttles the data going to users. It does not block data based on reaching 
a quota.

The overall bandwidth limit affects the traffic between the Web Security appliance and web servers for 
all users on the network.

To define an overall bandwidth limit:

Navigate to the Web Security Manager > Overall Bandwidth Limits page.

Select the Limit to option.

Enter the amount of traffic to limit in either Megabits per second (Mbps) or kilobits per second (kbps).

Submit and commit your changes.
