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

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

Extreme Networks switch
extreme#enable sflow port 2

Hewlett-Packard ProCurve
switches
hp#enable Password:***** hp#configure
terminal
hp# sflow 1 sampling A1,A2,A2 256
[ sflow 1 sampling <modules> <sampling rate>]
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 <NFA_HOME>/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
