Wireless Access Point
Configuring the Wireless AP 189
NetFlow
This window allows you to enable or disable the sending of NetFlow information
to a designated collector. NetFlow is a proprietary but open network protocol
developed by Cisco Systems for collecting IP traffic information. When NetFlow
is enabled, the AP will send IP flow information (traffic statistics) to the
designated collector.
Figure 112. NetFlow
NetFlow sends per-flow network traffic information from the AP. Network
managers can use a NetFlow collector to view the statistics on a per-flow basis
and use this information to make key decisions. Knowing how many packets and
bytes are sent to and from certain IP addresses or across specific network
interfaces allows administrators to track usage by various areas. Traffic flow
information may be used to engineer networks for better performance.
Procedure for Configuring NetFlow
1. Enable NetFlow: Select one of the Netflow versions to enable NetFlow
functionality: v5, v9, or IPFIX. Internet Protocol Flow Information Export
(IPFIX) is an IETF protocol (www.ietf.org) performing many of the same
functions as Netflow. Choose Disable if you wish to disable this feature.
2. NetFlow Collector Host (Domain or IP): If you enabled NetFlow, enter
the domain name or IP address of the collector.
3. NetFlow Collector Port: If you enabled NetFlow, enter the port on the
collector host to which to send data.
If you select IPFIX, 64 bit counters are supported starting with Release 7.1.
IPFIX uses IF-MIB, whose ifXTables support 64 bit counters.
