This blog explains how to export sFlow from ZTE and Edge-Core switches.
ZTE switches
The sFlow commands for these switches are as follows:
sFlow commands
sflow enable
sflow agent-config ipv4-address <Source IP Address>
sflow collector-config ipv4-address <Destination IP Address> <UDP Port>
For each interface:
interface <interface name>
sflow-sample-rate ingress <sample rate>
sflow-sample-rate egress <sample rate>
exit
Sample configuration
sflow enable
sflow agent-config ipv4-address 192.168.2.100
sflow collector-config ipv4-address 192.168.2.210 9996
interface gei_0/1
sflow-sample-rate ingress 1024
sflow-sample-rate egress 1024
exit
Note: Ingress and Egress should be enabled on all the interfaces, and the sample rate for both should be the same.
Edge-Core switches
The following are the commands enabled on these switches to export sFlow information:
sFlow commands
sflow receiver <exporter ID> Destination IP Address> port <UDP Port>
For each interface:
interface <interface name>
sflow flow-sampling <sample rate> <exporter ID>
sflow counter-sampling <poll counter> <exporter ID>
Sample configuration
sflow receiver 1 192.168.2.210 port 9996
interface te1
sflow flow-sampling 1024 1
sflow counter-sampling 30 1
No additional configuration is required apart from configuring these devices to export sFlow (the one mentioned above) at a product level as it will automatically capture the packets reaching the server on UDP port 9996 and start displaying the data.
