NetFlow Export Source Access List
By default, Cisco NetFlow Collector collects from any device that sends NetFlow data to it. However,
by specifying a NetFlow Export Source Access List, you can configure Cisco NetFlow Collector to reject
data from certain devices or to accept data only from certain devices.
Note The collector must be restarted for configuration changes to the source access list to take effect.
Click on the NetFlow Export Source Access List folder of the navigation tree to display the current
access list, as shown in Figure 2-18. If Action is Permit, NetFlow data is permitted only from the
selected devices and groups; if Action is Deny, NetFlow data is rejected from the selected devices and
groups.
