sFlow Agent
Configuring sFlow Using the Web Browser Interface
Figure 13-4. Special Features > sFlow > Flow Sampling Screen
The Wireless Edge Services zl 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.)
