x4012 high availability configuration?

QSFP stands for Quad Small Form-factor Pluggable. These ports can operate at 40G, and most have a breakout cable which allows the port to operate at four independent 10G interfaces. The X4012 does not offer QSFP ports.

The X-series does support link aggregation. Link aggregation will provide link redundancy. You can read more about link aggregation and it's configuration on page 190 of the user guide.

The X-series spec sheet can help show the different features of the switch.

Hi Daniel,

Can you renew the links, one is unknown and one needs a partner login, I would like to read the LAG config.

Thanks

Eric

Sorry about those links not working. I have links to all the KB articles, firmware and manuals

Let me know if the information you are looking for is not listed.

Thank you Daniel, that was very helpful, maybe you could point me in the right direction for a puzzle I have with 2 x 4012 switches and 2 x M3024 switches.

I am using the x4012s to connect to a Nutanix environment and the 3024s are TOR, as the 4012 switches are not stackable I have to connect them via ports on the front, as a LAG, the 3024 switches are stackable and I had a cable from each of the 4012 switches to each of the 3024 switches using a LAG - and that is where the problems start, as it seems to cause a loop so now i have no access and I am waiting for Remote Hands to power the 4012 off that I added the LAG to last :-(

Any ideas where I might find the answer?

Many thanks

Eric

I am not sure there is really much else you can do remotely. Once you have physical access to the switch, I would double check the physical port connections to ensure that the LAG configuration is using the correct port numbers. In most situations I tend to recommend LACP, it seems to work better in a stacking environment. Also check the switch logs to help find clues as to why this may have occurred.
