sFlow Agent
Configuring sFlow Using the Web Browser Interface
9. From the 802.11 Map drop-down menu, choose how the module’s sFlow
agent creates the sample.
The default setting is Unchanged; the module creates the sample as spec-
ified by the 802.11 extensions to sFlow. For example, it includes the 802.11
header.
If your sFlow receiver does not support the 802.11 extension, select
Convert to Ethernet from the drop-down menu. The module’s sFlow agent
then packages 802.11 samples to appear as Ethernet samples.
Note that some receivers, such as PCM Plus, automatically set this option
to match their capabilities.
10. Click the OK button.
The value in the Time Out field begins to decrement immediately. When the
timeout reaches zero, the Wireless Edge Services xl Module erases the Owner
and Receiver Address fields and returns all other fields to their default settings.
Set the Time Out value high enough that the module can implement sFlow
without frequent reconfiguration.
Manually Activating Flow Sampling
The Wireless Edge Services xl Module’s sFlow agent creates six separate
sampling instances for each of its adopted RP radios. By default, however,
flow sampling is disabled on all instances.
To view the configuration for flow sampling, select Special Features > sFlow
and select the Flow Sampling tab.
The screen lists every radio adopted by this module. The Data Source column
lists each radio’s index number and name. As you can see in Figure 14-4, each
radio is listed three times: once for each of the three flow sampling sFlow
instances that are available for configuration through the Web browser inter-
face. At factory defaults, the sampling instances have not been mapped to
receiver instances and the sampling rate is 0—in other words, flow sampling
is disabled.
