NimbostratusSFlow 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 n...
"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.

NimbostratusThanks 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.
