### This article will describe everything about sFLOW from hardware side
|
||
|
|
|
||
|
|
Please be aware! Extreme XOS operating system before 15.4 release lack of support for ingress sflow, only for egress ([source](http://extrcdn.extremenetworks.com/wp-content/uploads/2014/01/EXOS_Command_Reference_Guide_15_4.pdf)). Please use 15.4 version or more recent.
|
||
|
|
|
||
|
|
Example of sFLOW configuration for Extreme XOS:
|
||
|
|
```bash
|
||
|
|
configure sflow collector 10.0.2.33 port 6343 vr "VR-Default" # add collector
|
||
|
|
configure sflow agent 10.0.2.15 # agent address
|
||
|
|
configure sflow poll-interval 1 # send data to collector once per second
|
||
|
|
configure sflow sample-rate 1024 # sampling rate
|
||
|
|
enable sflow ports 1:39,1:40,2:39 # add ports to sFLOW monitoring
|
||
|
|
enable sflow # enable sflow globally
|
||
|
|
```
|
||
|
|
|
||
|
|
Check configuration for correctness:
|
||
|
|
```bash
|
||
|
|
show sflow
|
||
|
|
|
||
|
|
