ExtremeSwitching (EXOS)

We have two x690 stacks mlag together (each stack is a 48 port sfp+ and 48 port 10g copper). They run the core of our network and use VRRP between them. I’m considering upgrading to the new release that came out on May 30th. It’s been almost 60 days now. Any reservations on this code level? All important uplinks are cross connected (mlag) between both cores. A few devices or links only have one handoff, but there’s a port reserved in the opposite stack preconfigured for those situations. I would just have to move those cables and the upgrade the one stack. Then move them back and upgrade the other. How long is the stack down for? Should we wait a little longer, perhaps until the first patch level is released? What’s best practices? We have a lot of Cisco gear but would love to hear Extreme’s point of view. Looking forward to the ping protection feature which is fixed in 22.5. Should I have XMC update the firmware, or log in and do it manually? I have an X460 test switch that upgraded smoothly via XMC. Thanks for your advice

I am proposing this update in a maintenance window on Saturday August 25th after hours on our two core switch stacks. Hopefully that is enough time from its release to consider this version baked. I may open a case with gtac just to gauge official opinion closer to that date.

Now both cores use vrrp and this will be our first true test while in production as the core of our network doing an update. We've done it last year before it was in production so that is why I want to ensure this release will be a good one.

Saturday August 25th is about a week away. This post was here for 4 weeks and not a single response? Is anybody out there?

I've deployed this version and so far haven't seen any issues. As for time to upgrade, I would hazard to guess 10 minutes, probably quicker, just depends on the usual variables. If there is a boot prom upgrade involved it takes longer than an upgrade that doesn't.

Hi Guys,

I've already deployed the 22.5.1 on X690 Cores about a month ago and it is fine (until now).

Best regards,

Upgraded without any issues. Was happy to see that the VRRP and redundant connections from servers and other switch uplinks meant little to no downtime. I just had to swing a few cables for a few circuits that have single physical cable handoffs, but with cables prerun and labeled and quick timing, it went smoothly.

Thanks for all participation.

Until now? What happened?

Until now everything is fine... No issues after the upgrade were noticed...

Glad to hear that so far everything is fine. I will install the update this Saturday afternoon. We have two X690 stacks as cores running vrrp. I just have to swing the internet feed from one core to the other (ports preconfigured) so when the first one reboots it doesn't disconnect us from the world. Then I have to swing it back so I can reboot the second X690 core stack.

A lot of customers don't put nearly as much forethought into an upgrade as it seems you did. Thanks for that :)
Glad things went well!
