12. Create a virtual server that is used to classify the frames for Contract 1 and assign the virtual
server IP address for this server. Assign the BWM contract to the virtual server. Repeat this
procedure for a second virtual server.
Note:
This classification applies to the services within the virtual server and not to the virtual
server itself.
The classification rule for these BWM contracts is based on a virtual service. One of the BWM
contracts is applied to any frames that are sent to the virtual server associated with that
contract.
13. Apply and verify the configuration.
Examine the resulting information. If any settings are incorrect, make the appropriate changes.
14. Save your new configuration changes.
15. Check the bandwidth management information.
Check that all BWM contract parameters are set correctly. If necessary, make any appropriate
configuration changes and then check the information again.
Example
Configuring Content-Intelligent Bandwidth Management
Content-intelligent BWM allows the network administrator or Web site manager to control bandwidth
based on Layer 7 content such as URLs, HTTP headers, or cookies.
All three types of Bandwidth Management are accomplished by following the configuration guidelines
on content load balancing described in
Content-Intelligent Server Load Balancing, page 219
Application Redirection, page 455
. You also need to assign a contract to each defined string, where
the string is contained in a URL, an HTTP header, or a cookie.
BWM based on Layer 7 content gives Web site managers the following capabilities:
•
Ability to allocate bandwidth based on the type of request.
>> BWM Contract 2# ena
>> BWM Contract 2# /cfg/slb/virt 1/service 80/cont
1
>> Virtual Server 1# vip 100.2.16.2
>> Virtual Server 1# ena
>> Virtual Server 1# /cfg/slb/virt 2/cont 2
>> Virtual Server 2# vip 100.2.16.3
>> Virtual Server 2# ena
