How to set up sFlow on Dell Networking Switches running OS 9

https://dell.to/46N3UTN

when i try to configure on my N3224T i hit error when configuring the interface 

firmware version is 6.8.1.2.

SWITCH(config)#sflow 1 destination 172.16.xx.xxx

SWITCH(config)#sflow 1 polling gigabitethernet 1/0/1

Command not found / Incomplete command. Use ? to list commands.

Hello,

can you try to do the second command in interface mode?

Here the manual for the command pag 2238

Dell EMC Networking N-Series Switches CLI Reference Guide version 6.7.0

Thanks

when i try in interface mode

Gi1/0/48      Incorrect input! Invalid Receiver index value.
SWITCH01(config-if-Gi1/0/48)#sflow 1 polling ?

<interval>               Enter interval <0 - 86400>.

SWITCH01(config-if-Gi1/0/48)#sflow 1 polling 86400

SWITCH01(config-if-Gi1/0/48)#sflow 1 polling 1500 50

why do i not see the sflow commands when i do show running-config ??

Hi,

I'm not sure if the error comes from unfinished definition of the destination, let's try using the guide:

console(config)#sflow 1 destination owner 1 timeout 2000
console(config)#sflow 1 destination maxdatagram 500
console(config)#sflow 1 destination 172.16.xx.xxx 560

After this, 

console(config)#sflow 1 polling gigabitethernet 1/0/1 200 (try inserting poll-interval as previous config you did not) 

the command works, but OPManager will keep trying to add the switch with no result

What do you mean? Can you explain to me what you want to achieve with opmanager? And with this configuration?

i am trying to add N series switch to OpManager for Flow Analysis.

is this supported or recommended to enable sflow in Dell N3248TE-ON switch??

I beleive after enabling sFlow on the switch, you can set up OpManager to collect and analyze the sFlow data. I don't have much information about OpManager so please refer to the OpManager documentation.

is there any difference in configurations for N3224T and N3224P series switch ??

after i add the config to N3224T, the sflow command will "disappear"

sflow 1 destination owner SFLOW timeout 1000
sflow 1 polling tengigabitethernet 1/0/3 30
sflow 1 sampling tengigabitethernet 1/0/3 1024
