| Configuring the WSM using Device Manager |
The following table describes the fields on the Bandwidth Management Traffic Policies tab and Insert Traffic Policies dialog box.
Policy
The unique index number of the BWM traffic policy: 1 to 64.
Under Soft Limit TOS Value
The profile state of IP Type of Service (TOS) in the traffic policy: 0 to 255. The default is 0.
Over Soft Limit TOS Value
The profile state of IP Type of Service (TOS) in the traffic policy: 0 to 255. The default is 0.
Hard (Maximum) Limit
The hard speed limit for the traffic policy: 250k to 5,000k or 1M to 1,000M. The default is 2,000k.
This is a "never exceed" rate. A bandwidth class is never allowed to transmit above this rate. Typically, traffic bursts between the soft limit and the hard limit are charged a premium. The maximum hard limit for a band-width policy is 1 Gbps, even when multiple Gigabit ports are trunked.
Soft Limit
The soft speed limit for the traffic policy: 250k to 5,000k or 1M to 1,000M. The default is 1,000k.
This is the desired bandwidth rate, that is, the rate the customer has agreed to pay on a regular basis. When output bandwidth is available, a bandwidth class will be allowed to send data at this rate. No exceptional condition will be reported when the data rate does not exceed this limit.
Reserve (Minimum) Limit
The reservation speed limit for the traffic policy: 250k to 5,000k or 1M to 1,000M. The default is 500k.
Also called Committed Information Rate (CIR), this is a rate that a bandwidth classification is always guaranteed. In configuring BWM contracts, ensure that the sum of all committed information rates never exceeds the link speeds associated with ports on which the traffic is transmitted. In a case where the total CIRs exceed the out-bound port bandwidth, the WSM will perform a graceful degradation of all traffic on the associated ports.
Buffer Limit
The buffer limit for the traffic policy: 8,192 to 128,000 bytes. The default is 16,320.
