sFlow Flow Sampler Settings

This table is used to create sFlow flow sampler settings on the Switch. By configuring the sampling function for a port,
a sample packet received by this port will be encapsulated and forwarded to the analyzer server depending on active
rate.
To view this window, click Monitoring > sFlow > sFlow Flow Sampler Settings, as shown below:
The following parameters can be configured:

Up to four sFlow Analyzer Servers can be configured.
The entity making use of this sflow analyzer server.
The length of time before the server is timed out. When the analyzer server times out, all
of the flow samplers and counter pollers associated with this analyzer server will be
deleted. "Infinite" indicates that the analyzer server will never time out. If not specified, the
default value is 400.
The IP address of the analyzer server. If not specified, the address will be 0.0.0.0 which
means that the entry will be inactive.
The destination UDP port for sending the sFlow datagrams. If not specified, the default
value is 6364.
The maximum number of data bytes that can be packed in a single sample datagram. If
not specified, the default value is 1400.

Description
Specifies the port or list of ports to be configured.
The analyzer server id specifies the ID of a server analyzer where the packet will be
forwarded.
The sampling rate for packet sampling. The actual rate is the configured rate value
multiplied by 256. For example, if the rate is 20, the actual rate 5120. One packet will be
sampled from about 5120 packets. If set to 0, the sampler is disabled. If the rate is not
specified, its default value is 0.
The maximum number of leading bytes in the packet which will be sampled, encapsulated
and forwarded to the server. If not specified, the default value is 128.
