Support >How to configure sFlow on ECS2100 series (firmware version 1.2.2.0 and above) and verify with sFlowTrend
Introduction on sFlow:
sFlow, short for "sampled flow".
  • sFlow is an industry standard, provided by a wide range of network equipment and software application vendors.
  • sFlow provides a network-wide view of usage and active routes. It is a scalable technique for measuring network traffic, collecting, storing, and analyzing traffic data. This enables tens of thousands of interfaces to be monitored from a single location.
Topology:



At the ECS2100 series, this feature is a new enhancement on phase 2 firmware. (v1.2.2.0 and above.)
Here is the sample showing how to configure sFlow on ECS2100-28PP.
 
Switch's Configuration:

1. Configure the management IP address on switch.
Console# configure
Console(config)# interface vlan 1
Console(config-if)# ip address 192.168.2.10/24

2. Create a sFlow owner and specific the destination IP address.
Console# sflow owner TEST timeout 10000000 destination 192.168.2.100 port 6343 version v5
  • The allowed range of timeout: 30 – 10000000 sec
  • It supports the following sFlow versions: v4 / v5
3. Specific the monitored port and the receiver.
Console# sflow sampling interface ethernet 1/2 instance 1 receiver TEST sampling-rate 256
  • The allowed range of the sampling-rate: 2 – 65535

It means the number of packets out of which one sample will be taken.
When the sampling-rate is bigger, the sampling will be slower.
 
4.Check the sFlow status.
