SFlow routing

Hi All,

I want to setup SFlow sending to a Solarwinds(SW) server. The standard polling is between the SW server and the mgmt. port. Will SFlow use the same mgmt. interface and route or will I need to setup a static route? If I need to setup a static route will that affect the current SW to F5 mgmt traffic path?

Thanks in advance

"sFlow traffic will use only the self IP address of the BIG-IP system as the egress interface": https://support.f5.com/kb/en-us/solutions/public/15000/100/sol15193.html

Not possible to use the management interface since 11.4.0.

Thanks for the reply Eric. Do you know why the destination address must be in a local subnet?

The explanation that I've seen before is that if you're processing a lot of sFlow data (i.e. on multiple 40 Gbit interfaces) it would be possible to saturate the 1 Gbit management port. If the sFlow collector is only accessible via the mgmt interface it is possible to create an isolated route domain (using a data plane interface) that sits on the same network as the mgmt interface and reference the collector by route domain notation (i.e. mgmt: 192.168.1.245/24, tmm_mgmt_rd1: 192.168.1.246%1/24, sFlow target: 192.168.1.10%1). Depending on preference/network policy this may or may not be desirable.

Thanks. I understand the possibility of mgmt. interface saturation but was curious why the destination would be limited to a local subnet. I've linked the Sflow output to a local firewall and NET'td the connection. I just need to get data through the device to see if it all works. I'll add a post once once I have it working. Thanks for you responses they're greatly appreciated.

How was your testing Deee-blue? I'm configure the sflow output through self ip but getting no data in Top 100 Conversations.
