LACP not working

Ok. You can purchase support from us but not on-site.

It's showing the peer as having a different ID/MAC address now. Did you swap the ports in use in pfSense? Different priorities there also, 5&6 vs 3&4 previously. Something has changed there.

Also there is no-where in Europe it's 2am yet, what timezone is that switch set to?

Steve

the switch is in Europe +1. do you think the time is the cause?
we are based in Germany. do you think different on the time would cause this?

I see it one day ahead than the normal time. 1 Dec
there is nothing changed on the switch or cables are still the same as before.

Wednesday they arranged a engineer who will come on site to check and assist. if he cannot help I can reach out for you guys, but time different is going to be difficult.

I doubt the clock offset would cause a problem for lagg. It does show the switch is either not configured for ntp though or unable to reach it. Or just set the wrong timezone, and not UTC.

Previously the switch logs were showing this:

lag's peer info (priority=32768,id=e839.3511.faab,key=715)

That's the expected ID, it matches the MAC address of lagg0 in pfSense.
So what is this new ID? Is that a MAC you recognise?

It throws doubt on what is physically connected to what.

this possibly because I connected last time two different cables. to test.
have port em2 em 3 connected to port 8 on each switch and ebc1 and etc 2 on port 2 on each switch.
maybe that why? the currenty lag is running on the port 2 on each switch. I can disable that lacp and try port 8 lacp.
I have tried on a different port group 8 on each switch and this error shows up.
so appear I have to configure priority on the lag, but don't know where and how. never seen it before.

Nov 30 23:43:40:I:System: dynamic lag interface 1/1/8's peer info (priority=3,id=e839.3511.faab,key=0) mis-matches with lag's peer info (priority=32768,id=e839.3511.faab,key=363), set to mismatch Error

stephenw10

Seems more like you have to omit the priority in the switch/port to have it match what looks like the default value pfSense is sending. But it's not something I've had to do before.

Steve

stephenw10

In fact there is no way to set a priority in pfSense:

https://www.freebsd.org/cgi/man.cgi?lagg(4)#BUGS

     There is no way to	configure LACP administrative variables, including
     system and	port priorities.  The current implementation always performs
     active-mode LACP and uses 0x8000 as system	and port priorities.

So that must be in the switch config somewhere. It looks like it's set to 0 in the output you have posted but there must be somewhere else it's pulling in that value.

Hi Steve,
today we had a call with pfsense engineer, however the issue appear the switch still.

the pfsense is sending LACP and binding the ports nicely.
but the switch is still blocking the ports and we cannot see any log neither on the switch or the firewall.
the issue still remains unresolved unfortunately.

stephenw10

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

@stephenw10 said in LACP not working:

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.
