4. Add the filter to an ingress port on Alteon.
5. In the BWM configuration, enable IP limiting.
6. Determine whether the user should be identified by source or destination IP address.
— If the contract is used for traffic going out to the Internet, define it by the source IP address:
iptype sip.
— If the contract is used to limit the amount of traffic downloaded from the user by a client on
the Internet, define it by the destination IP address: iptype dip.
7. Disable traffic shaping on this contract. Traffic shaping cannot be used in user-level rate limiting
contracts.
8. Apply and save the configuration.
9. View the current per-user BWM sessions for the active contract.
Example Configuring BWM Preferential Services
BWM can be used to provide preferential treatment to certain traffic, based on source IP blocks,
applications, URL paths, or cookies. You may find it useful to configure higher policy rate limits for
specific sites, for example, those used for e-commerce.
In this example, there are two Web sites, "A.com" and "B.com." BWM is configured to give
preference to traffic sent to Web site "B.com:"
1. Configure Alteon as you normally would for SLB. Configuration includes the following tasks:
— Assign an IP address to each of the real servers in the server pool.
— Define an IP interface on Alteon.
— Define each real server.
— Define a real server group.
— Define a virtual server.
— Define the port configuration.
