— Define each real server.
— Define a real server group.
— Define a virtual server.
— Define the port configuration.
Note: Ensure BWM is enabled on Alteon (/cfg/bwm/on).
2. Select a bandwidth policy. Each policy must have a number from 1 to 512.
3. Set the hard, soft, and reserved rate limits for this policy in kilobytes.
4. Set a parameter between 8192 and 128000 bytes. The buffer depth for a BWM contract should
be set to a multiple of the packet size.
5. On Alteon, select a BWM contract and name the contract. Each contract must have a unique
number from 1 to 1024.
6. Set the bandwidth policy for the contract. Each BWM contract must be assigned a bandwidth
policy.
7. Enable the BWM contract.
8. Create a filter that will be used to classify the frames for this contract and assign the BWM
contract to the filter.
The classification rule for this BWM contract is based on a filter configured to match ICMP traffic.
The contract will be applied to any frames that match this filter.
>> # /cfg/bwm/pol 1
>> Policy 1# hard 250k
>> Policy 1# soft 250k
>> Policy 1# resv 250k
(Set "never exceed" rate)
(Set desired bandwidth rate)
(Set committed information rate)
>> Policy 1# buffer 8192
>> Bandwidth Management# /cfg/bwm/cont 1
>> BWM contract 1# name icmp
>> BWM Contract 1# pol 1
>> BWM Contract 1# ena
>> BW Contract 1# /cfg/slb/filt 1/proto icmp
>> Filter 1# adv/icmp any
>> Filter 1 Advanced# cont 1
>> Filter 1 Advanced# /cfg/slb/filt 1/ena
>> Filter 1# apply
(Define protocol affected by filter)
(Set the ICMP message type)
(Assign BWM Contract 1 to this
filter)
(Enable this filter)
(Port and enable filtering)
