Dear Folks,

I am planning to proceed with the foundation imaging of our Nutanix NX-8170-G9 nodes using a standalone 1GbE switch (small 6 port) . For the initial setup, I will connect the BMC port and the AIOM port (for CVM traffic) to this switch and it will configure Active/Backup.

Each node is equipped with two 10GbE LC fibre ports, currently intended for CVM and VM traffic via LACP bonding. My question is:

Post-foundation, how can I transition from the temporary 1GbE Active/Backup setup to the intended LACP configuration on the 10GbE interfaces?

  • Is it possible to perform this change via the Prism Element GUI,
  • Or is it necessary to access the CLI through the IPMI console?
  • Could you please outline the recommended procedure

Thx Calvin

Hey Calvin,

Yes this is perfectly fine a lot of people build like this with a laptop and flat switch with the hosts.

Yes you can switch it after using the GUI, I'd first switch to active/backup using your 10G links and confirm that works, then remove the 1Gs before switching to LACP and leave fallback enabled on the switches just incase.

Cheers,

 

Kim..

Thanks Kim.

 

So, with fallback enabled on the switches, it should still function correctly even if the Nutanix side is configured as active/backup—right?

The plan would be to remove the 1G link, verify that traffic is passing through the currently configured active/backup setup, and then change the switch bonding mode to LACP via Prism Element. For troubleshooting purposes, access to the CLI through IPMI would be the correct approach—have I understood that properly?

 

Cheers

Yep, fallback is good to have enabled when you change from 10GbE active/backup to active/active LACP. It just means if lacp doesn't establish the host will still work with the switch.

If you lose access to the host during any of this then you can use the IPMI onto the host and from the host you can reach the CVM internally as needed.
