I have a trouble using the sFlow v5 sensor with Cisco Nexus 3048 devices. So, when i just add sFlov v5 sensor, all is fine, the toplist is generating for all flows coming from nexus switch, which is normal. But, it seems that is not working well with filters.
Yes, i know that the Interface filter is accepting only the ifindex value. Here are the results of "show interface snmp-ifindex" command on nexus switch:
I have several devices monitored via sflow (some HP switches) and the Interface filter is working well. In case with Nexus switches, its not working at all (This sensor has not received any data).
I used "PRTG SFlow tester" and here are the results.
- Flows: https://pastebin.com/XzKB8Wt0
- Debug: https://pastebin.com/A6vkHtP7
For now, i have sflow enabled for interfaces po100, po240 and ethernet 1/24. As we can see in flows, the interfaces are matching ifindex values (for example po100 = 369098851 in this flow "18.104.22.168:443->22.214.171.124:23314 P:6 IF/OF:369098991/369098851 07:53:09 3394485780480").
So the problem is that PRTG is processing well the raw flows, but when i create other sensor with Interface filter -> no result, no data.
