7. On Alteon, select a BWM contract and, optionally, a name for the contract. Each contract must
have a unique number from 1 to 256.
8. Optionally, set a precedence value for the BWM contract.
Each contract can be given a precedence value from 1 to 255. The higher the number, the higher
the precedence. If a frame is applicable to different classifications, then the contract with the
higher precedence is assigned to the frame. If the precedence is the same for the applicable
contracts, then the following order will be used to assign the contract to the frame:
a. Incoming port
b. VLAN
c. Filter
d. Service on the virtual server
e. URL/cookie
9. Optionally, enable TOS overwriting for the BWM contract.
10. Set the bandwidth policy for this contract. Each bandwidth management contract must be
assigned a bandwidth policy.
11. Optionally, enable traffic shaping. Rate limiting is enabled by default. Enabling traffic shaping
disables rate limiting. For more information, see Traffic Shaping, page 769
.
12. Enable the BWM contract.
13. Classify the frames for this contract and assign the BWM contract to the filter or virtual IP
address.
Each BWM contract must be assigned a classification rule. The classification can be based on a
filter or services on the virtual server. Filters are used to create classification policies based on
the IP source address, IP destination address, TCP port number, UDP, and UDP port number.
In this case, all frames that match filter 1 or Virtual Server 1 will be assigned Contract 1.
14. On Alteon, apply and verify the configuration.
Examine the resulting information. If any settings are incorrect, make any appropriate changes.
