• Packet Flow Sampling: In this sampling, the data packets received on the ethernet interface of the device are
sampled based on a counter. With each packet received, the counter is decremented. When the counter reaches zero,
the packet is packaged and sent to the sFlow Receiver for analysis. These packets are referred to as Packet Flow
Samples.
• Counter Polling Sampling: In this sampling, the sFlow Agent sends counters periodically to the sFlow Receiver based
on the set polling interval. If polling interval is set to 5 seconds then the sFlow Agent sends counters to sFlow Receiver
every 5 seconds. These packets are referred to as Counter Polling Samples.
The Packet Flow Samples and Counter Polling Samples are collectively sent to the sFlow Receiver as sFlow Datagrams. It is
possible to enable either or both types of sampling.
sFlow Sampling effects the system performance and hence care must be taken in configuring the sFlow parameters. To
configure sFlow, navigate to MONITOR > Tools > sFlow. The following sFlow® screen appears:
Figure 7-33 sFLOW
This screen displays the following information about the sFlow Agent:
• Version: The version displayed is 1.3;Proxim Wireless Corp.; v6.4. The version comprises the following information:
1. sFlow MIB Version: Indicates the agent’s MIB version. The MIB specifies how the agent extracts and bundles
sampled data, and the sFlow receiver must support the agent’s MIB. The sFlow MIB version is 1.3. so the sFlow
Receiver’s version must also be at least 1.3.
2. Organization: Specifies the organization implementing sFlow Agent functionality on the device, that is, Proxim
Wireless Corp.
3. Revision: Specifies the sFlow Agent version, that is, v6.4.
• Address Type: Specifies the protocol version for IP addresses.
• Agent Address: Specifies the sFlow Agent’s IP address.
