Configuring sFlow Using the Web Browser Interface
Figure 14-4. Special Features > sFlow > Flow Sampling Screen
The Wireless Edge Services xl Module’s sFlow agent begins sampling a flow
when either of two conditions are met:
■ An sFlow receiver contacts the module’s sFlow agent and claims an open
flow sampling instance (the Receiver Instance column displays 0). In this
case, the receiver configures the sampling rate.
■ You map the flow sampling sFlow instance to a manually configured
receiver instance. In this case, you set the sampling rate.
Follow these steps to enable flow sampling:
1. Select Special Features > sFlow and select the Flow Sampling tab.
2. Select one of the sFlow instances on the radio for which you want to
sample the traffic.
3. Click the Edit button. The Flow Sampling Configuration screen is displayed.
This screen displays the radio in question in the Data Source field. The
sFlow Instance field indicates which of the six instances for this radio you
are configuring. (You cannot alter the number for the sFlow instance. To
configure a different instance number, return to the main screen and
select that instance instead.)
