User/Application Fairness Example
Bandwidth Management can be applied to prevent heavy bursters from locking out other users,
such as in preventing the following:
n
Customers using broadband access (such as DSL) from blocking dial-up customers
n
Customers from the same hosting facility locking out each other because of flash crowd
n
FTP from locking out Telnet
n
Rate 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.

2. Set the hard, soft, and reserved rate limits for the bandwidth policy, in Mbps.

>> Policy 1# hard 5 (Set “never exceed” rate)
>> Policy 1# soft 4 (Set desired bandwidth rate)
>> Policy 1# resv 3 (Set committed information rate)
