Peak Rate
Every traffic class can be configured with a peak rate parameter, which is
the bandwidth that can be offered to that class if unused bandwidth is
available from other classes. This provides for very efficient bandwidth
utilization. A class can be configured to borrow whatever bandwidth is
available from its parent class up to the PR limit set for that class.
To prevent a class from borrowing, set the CR equal to the PR. Also, note
that a class cannot borrow more than the bundle bandwidth.
Classification Types
The example in Figure 19.1 reserves the largest CR(1536 Kbps) for two
servers, 10.1.1.1 and 10.1.1.2, which are members of the SrcOne class.
The remainder of the 10.1.1.0/24 subnet is assigned to the SrcTwo class and is
configured with a CR of 1024 Kbps. Additionally, the SrcTwo class is further
divided into application port classes. All other hosts in Figure 19.1, the default
class, are configured for a CR of 512 Kbps.
The classification type must be the same across a given level of traffic class.
Note in Figure 19.1, that the classification type at the first level traffic class is
the source IP address; for the second level, the classification type is the
application port. Because bandwidth limitations are evaluated from most
specific to least specific, 10.1.1.1/32 falls within the SrcOne class.
