After upgrade from 24.11 to 25.0.7.1 lagg port did not work

stephenw10

Hmm, it's a lagg with one member port? Cross chassis?

along5664

@stephenw10
There are two ports in the port channel. I only showed one port off our 9k, the other 9k has the same port configuration.
Note this works fine in 24.11 but did not work on 25.07.01 when I did the upgrade.
This is the first pfsense I have upgraded using lagg ports.

Here are the configs:

Hmm, did you try enabling the lacp debug?

I've not seen any issues with LACP in 25.07.1. I have a number running here and it's very widely used.

@stephenw10
I have a support ticket opened, but here is what I saw:
I will roll back to 24.11 as this is standby unit for production.

Here is all the information I collected while on 25.07.1, All ports are working except the lagg port. I tried slow and fast , no change
This is what I see at my switch. While on 25.07.1 on both switch ports
SLC-SHRD-CORE-SW-01# sh int e1/31
Ethernet1/31 is down (suspended(no LACP PDUs))

Can we assume that the ix0 and ix1 ports showed as UP and linked at 10G though when that happened?

Still slightly confused by the port down logs. We need to determine if this is some change in the ix driver causing link issues or in the lagg driver running over that.

As I say though both are commonly used and I'm not aware of any issues so this must be something subtle.

along5664

@stephenw10
I do see the ports come up on switch, then they go into susupend mode. Agree I think this is some driver issue or something causing pdu to not be sent. I am going to set this to a single port and run the upgrade without lagg to see if it works. Thanks for all the help.

along5664

This morning, I removed the lagg port and set the pfsense to use a single interface not in a lagg/lacp config.
The upgrade ran without any issues, and everything looks as it should.

For now we will change our devices to use only single ports and not lagg, until a solid resolution to the issues is discovered.
Thanks for all your help on this.

stephenw10

Hmm, so looks like a lagg/lacp issue then. Unless the ix driver is somehow dropping the pdus...

along5664

@stephenw10
We changed to using a sinlge port on our primary last night and the upgrade worked perfect, and port came up as expected. Def something with lagg/lacp.

stephenw10

OK I may have replicated this.... testing....

stephenw10

Hmm, maybe not. I was initially able see it fail to link but after rebooting it came up fine:

I assume you rebooted and it still failed?

along5664

@stephenw10
Yes I rebooted several times. Did not seem to change anything on our side.
We are working fine now on single port.
Thnaks for looking into this further.

stephenw10

Mmm, if this is something more general I'd love to pin it down. Can't find the steps to replicate it again now though. I'll keep trying...

I upgraded from 24.11 to 25.0.7.1 on my netgate 2100 yesterday night without a hitch - off course i took screen shots of my various configuration and did have previous boot backup (and xml)
