Hi,

 

Im trying to understand how a Nutanix node works fine even if it’s connected to two switches not in stack. And i found that only one interface is enable when using the active-backup mode, but when im checking on the switches i fount that both interfaces are up.

 

So, im asking if there is a way to check which interface is actif from AHV or CVM.

Hi @MMASLOUH 

The easiest way to check which interface is “Active” in an Active/Backup configuration is via Prism on the Network tab. There you’ll see a continuous line for your active interface and a “dotted” one with the passive interface. In the screenshot below the node is configured with balance-tcp so both interfaces appear as “Active”.

On the other hand you can take a look to this article https://portal.nutanix.com/page/documents/kbs/details?targetId=kA00e000000Xf2qCAC

You launch the command ovs-appctl bond/show br0-up from your AHV host and you’ll get an output similar to this one

Where eth2 is the “Active” interface and eth3 the backup interface

Hope this helps
