enable sflow on dell s series switch for Opmanager
I am trying to configure sflow on my S series S31XX switches to send flow data to OPManager, but seems to hit error.
OPManager not able to configure the switch and even if i manually configure on the switch, it does not work.
switch not added to OPManager for sflow.
sflow collector 172.16.xx.xx agent-addr 172.16.xx.xx max-datagram-size 400
sflow enable
sflow extended-switch enable
sflow polling-interval 60
sflow max-header-size extended
No Events found!

Hi,
Can you elaborate on you mentioned "OPManager not able to configure the switch"? Is it that it is unable to discover the device? Can the switch ping the OPManager, is it reachable? When you do a show sflow; what is the output? What is your firmware version of the switch?

OPManager is not able to add S series switch for flow analysis.
this is the output for sflow
S3148#show sflow
sFlow services are enabled
Egress Management Interface sFlow services are disabled
Global default sampling rate: 4096
Global default counter polling interval: 600
Global default extended maximum header size: 256 bytes
Global extended information enabled: switch
1 collectors configured
Collector IP addr: 172.16.0.xxx, Agent IP addr: 172.16.0.xxx, UDP port: 6343 VRF: Default
38 UDP packets exported
0 UDP packets dropped
6 sFlow samples collected
firmware version is 9.14(2.12)
i managed to add S5248 on OS10 but not S3148 switch

Hi,
Looks like the switch is configured correctly. Is the sFlow collection that you configured is the management port or data port?
What error does OPmanager appear?

Hi,
Can you remove max-datagram-size 400 from your sFlow config based on "sflow collector 172.16.xx.xx agent-addr 172.16.xx.xx max-datagram-size 400"

have already changed the config to this
sflow collector 172.16.0.xx agent-addr 172.16.0.xx
sflow enable
sflow extended-switch enable
sflow polling-interval 600
sflow max-header-size extended

Hi,
After reconfig, OPManager still having the same issue? Can I check if OPManager has how many switches discovered now? How about if you were to remove some or as many, to check the issue? Have you tried contacting OPManager to reach out and check?
Also can I check for #agent-addr 172.16.0.xx is the IP of the switch management right?
Can you also add these commands:
#sflow polling-interval <15-86400> this value match with collector server setting
#sflow sample-rate <256-8388608> this value match with collector server setting
