I have a pair of Cisco Nexus 9372PX switches running NXOS version 7.0(3)I1(3). According to the link at http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/7-x/system_management/configuration/guide/b_Cisco_Nexus_9000_Series_NX-OS_System_Management_Configuration_Guide_7x/b_Cisco_Nexus_9000_Series_NX-OS_System_Management_Configuration_Guide_7x_chapter_011000.pdf, sFlow is supported on this switch and should be turned on using:

configure terminal
feature sflow

However, when I try this I get an error saying the command is invalid. When I run:

configure terminal
feature ?

... the sFlow feature isn't even listed!

I'm logged in as a network-admin user so don't believe this to be permissions related. Any thoughts on what I can try?

Make sure you check the prerequisites mentioned in that document:

For Cisco Nexus 9332PQ, 9372PX, 9372TX, and 93120TX switches and for Cisco Nexus 9396PX, 9396TX, and 93128TX switches with the N9K-M6PQ or N9K-M12PQ generic expansion module (GEM), you must configure the sFlow and SPAN ACL TCAM region sizes for any uplink ports that are to be configured as an sFlow data source.To do so, use the hardware access-list tcam region sflow and hardware access-list tcam region span commands.

  • Unfortunately, the command "hardware access-list tcam region sflow" doesn't work either :( switch1(config)# hardware access-list tcam region s span svi – Daniel Arkley Dec 29 '15 at 10:32
  • What exactly do you mean by 'logged in as network-admin'? What does `show privilege` say? – Teun Vink Dec 29 '15 at 10:40
  • User name: admin Current privilege level: -1 Feature privilege: Disabled – Daniel Arkley Dec 29 '15 at 15:15
  • Well, there you have it: `Feature privilege: Disabled` indicates you can't enable new features, which is exactly what you're doing. – Teun Vink Dec 29 '15 at 15:45
  • I'm logged in with the most privileged user account (admin, which is a member of the network-admin role) on the system, and I can enable any other feature on the switch such as hsrp, dhcp, lacp, lldp - it's just that sFlow doesn't appear as a feature to enable. – Daniel Arkley Dec 30 '15 at 21:20

It turns out that NXOS version 7.0(3)I1(3) does not offer sFlow. We need to upgrade to 7.0(3)I2(1) for that functionality.
