LACP not working

cyberbot

Yes, it looks like a switch issue to me too.

Have you been able to test a lagg to a single switch?

Check the full switch config from both switches. It must be pulling in the port priority from somewhere.

Steve

Hi Steve,
the priority we were able to fix it, with specifying the priority and the error of the flapping were gone, but the switch was still blocking the interfaces LAG

stephenw10

No longer logging the mismatch in the switch?

cyberbot

no, not on the switch and no flapping on the firewall,
but when we do show lag it still shows blocked LAG.

stephenw10

Can we see the current output from both sides?

cyberbot

@stephenw10

yes of course only there is no log now, nothing happening at all.

cyberbot

when I do show log on the switch nothing really happens about the LACP or errors neither on the pfsense

stephenw10

Ok but can we see ifconfig -vvv lagg0 from pfSense and show lag from the switch. The complete output from each.

The timeouts are back to short on the switch but do also look like they're set short in pfSense.

There are two additional sections in the 'show lag' output. The system lag info at the top and the partner info at the bottom. Both of which might be useful here.
For example:

Hi Steve,

do you suggest to reconfigure the set up to long instead of short?
i can do that is not a issue at all, but the switch still blocking it

stephenw10

Well it should work with either as long as both sides are set the same. The switch ports are not showing Exp (expired) which I would expect if pfSense was still using Long timeouts.

I know Long works though.

The port operational state (Ope) is still showing Err:

Err: If there is a peer information mismatch, then that particular port is moved to the Error disable state (Err).

https://docs.commscope.com/bundle/fastiron-08095-commandref/page/GUID-06AFF73D-6957-44A5-AF25-3527B2BE1580.html

I would have expected that to be logged still.

Can we see the full 'show lag' output?

on the switch side I don't see any logs showing anything about the LACP but only about the when I logging using ssh ect...
I have change it to long but still shows blocked.

We need to see the full output, including the partner info.

The first port there is showing it's not seeing ant LACP packets from the other side.

Hi Steve

What full output are you referring to ? On the pfsense or switch ?
On the switch side it shows only information about who is connected from the ssh and what time nothing else .

stephenw10

The complete output from show lag on the switch contains the Partner info and PDU stats at the end which show what is connected and on which port. It also shows the system wide lag parameters at the top on my switch. It would be good to compare those.
Your switches are different to mine though, the output is very similar but not identical.

You posted a more complete output here: https://forum.netgate.com/post/947906

Ok so from that we can see that the system ID the switch sees on both those ports matches the ID pfSense has set on it's lagg ports.

However we cannot see the switch system ID. pfSense sees it as: 0001,60-9C-9F-4B-80-8C

That info is at the top of the show lag output from the switch as I showed above:

SSH@ICX6450-24P Switch>show lag
Total number of LAGs:          1
Total number of deployed LAGs: 1
Total number of trunks created:1 (123 available)

LACP Long timeout:             90, default: 90
LACP Short timeout:            3, default: 3

It obviously should match but....

What we can see is that the switch has recorded precisely 0 lacpdus received.

what are you suggesting ?
if i connect a different switch the ports comes online and shows the LACP is fine.

stephenw10

To that switch or to pfSense?

I have once seen a similar issue to this that was eventually resolved by simply rebooting the switch stack. Something no-one had thought to do because generally switches do not require that sort of thing.

Beyond that I would try a lagg to ports on the same switch to remove the cross-chassis LACP as an issue.

Then I'm out of suggestions. You probably need to get Brocade/Rukus/Commscope support involved at that point.

Hi Steve
I can do the reboot tonight. When I am logged in shut reboot its will reboot both switches ?
