sFlow Agent
Configuring sFlow Using the Web Browser Interface
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 zl 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 reconfig-
uration.
Manually Activating Flow Sampling
The Wireless Edge Services zl 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 13-4, 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 interface. 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.
