I am running a Cisco 5508 Wireless Controller with Software Version 22.214.171.124. The goal is to have Netflow monitoring client usage to identify clients using to much traffic and where the total over all traffic is going or coming from.
I am running PRTG Network Monitor 126.96.36.19942 x64 with sensor Netflow v9 Custom. I have configured inside the WLC from:
Wireless > Netflow > Exporter
Name = PRTG
Exp IP = 10.x.x.x
Port = 9993
Wireless > Netflow > Monitor
Net Mon Name = PRTG_Netflow
Exp Name = PRTG
Record Name = Client App Record (Better Performance).
WLAN > WLAN ID X > QoS >
<Check Mark> Application Visibility
Netflow Monitor = PRTG_Netflow
Apply. At this point I was getting an error for AVC Profile, but it has disappeared.
Sensor Name: WLC Netflow v9
Receive NetFlow Packets on UDP Port: 9993
Sender IP: WLC Interface
The connection is made, but I am not getting the information inside the Tops, Talkers, Connections, Protocols. I am getting 100% information but no expected information.
I am understanding what AVC is used for. I am not trying to apply access list to access on the networks, just trying to configure data points to troubleshoot problems.
Any help on getting the acquired data?
From the manual:
I've marked the important parts red.
In other words, you get the expected results.
Have you defined a AVC policy (without any marking or control) & applied it to SSID ? Configuration should be simple, follow these posts, however you need to make sure your netflow collector understand flow format send by WLC
Even with 8.5 code, 5508 controller not supported fully v9.0 netflow, still it sends those customized flow records & you require your netflow collector understand that flow format
*** Pls rate all useful responses ***
Yes I have tried an empty AVC but inside PRTG I am showing one big gray circle saying other. There are no IPADDRs, protocols or talk talkes.
