User/Application Fairness Example

Bandwidth Management can be applied to prevent heavy bursters from locking out other users,
such as in preventing the following:
nCustomers using broadband access (such as DSL) from blocking dial-up customers
nCustomers from the same hosting facility locking out each other because of flash crowd
nFTP from locking out Telnet
nRate limit particular applications
In the following example, BWM is configured to prevent broadband customers from affecting
dial-up customer access. This is accomplished by setting higher bandwidth policy rate limits
for the port processing broadband traffic.
1. Select the first bandwidth policy.
Each policy must have a number from 1 to 64.
NOTE – Ensure BWM is enabled on the switch (/cfg/bwm/on).
2. Set the hard, soft, and reserved rate limits for the bandwidth policy, in Mbps.
>> # /cfg/bwm/pol 1 (Select BWM policy 1)
>> Policy 1# hard 5 (Set “never exceed” rate)
>> Policy 1# soft 4 (Set desired bandwidth rate)
>> Policy 1# resv 3 (Set committed information rate)
