Enabling sFlow

 

How do I enable sFlow ?

If your device supports sFlow, then you will have to enable sFlow on each of the interfaces that you want to collect flow statistics on.

Enabling sFlow on various devices

Foundry Networks switch

foundry2402#enable

Password:*****

foundry2402#configure terminal

foundry2402(config)# interface ethernet 10

foundry2402(config-if-e100-10)#sflow forwarding

foundry2402(config-if)#exit 
foundry2402(config)# sflow enable

foundry2402(config)# sflow destination 192.168.0.2 9996

foundry2402(config)# sflow sample 256

foundry2402(config)# sflow polling-interval 10

 

Important Please note that the part in red has to be repeated for each interface individually.

For more information on Foundry devices configuration refer to www.foundrynet.com

Force10 switch

force#enable

Password:*****

force#configure terminal

force(config-interface)#sflow enable 


[ This command has to be repeated for all interfaces. ] 

force(config)#sflow destination 192.168.0.2 9996 agent-addr 192.168.1.2

force(config)# sflow sample 256

force(config)# sflow polling 10

Extreme Networks switch

Please refer to the following documentation for configuring sFlow on Extreme Networks switch

extreme#enable sflow port 2

For more information on Extreme Network devices refer to www.extremenetworks.com

 

Hewlett-Packard ProCurve switches

hp#enable

Password:*****

hp#configure terminal

hp#
 sflow 1 sampling A1,A2,A2 256 [ sflow 1 sampling ]

hp# sflow 1 destination 192.168.0.2 9996

The above commands work only on latest HP devices.

sFlow can be enabled on some of the HP switches only through SNMP. We provide two script files for enabling and disabling sFlow on HP switch.

The script files SFlowEnable.bat / SFlowEnable.sh and SFlowDisable.bat / SFlowDisable.sh are present under  /troubleshooting folder.

For enabling sFlow you need to provide the below command:

SFlowEnable.bat switchIp snmpPort snmpWriteCommunity collecorIP collectorPort samplingRate

An example,

sFlowEnable.bat Hp2824 161 private 192.168.3.1 9996 256

For disabling sFlow you need to provide the below command:

sFlowDisable.bat switchIp snmpPort snmpWriteCommunity

An example,

sFlowDisable HpProcurve 161 private
