XG-7100 redundant connections to external switches

Sorry I was called away. That does work though:

I'll see if we can get a patch you can apply directly to 2.4.4p2 via the patches package. That would be cleaner.

Ok here's a patch you apply against 2.4.4p2. You can use the system patches package to do it which removes most of the scope for error.

Hmm I not getting running a trunk. (I have applied the patch above on 2.4.4P2)

I have configure on the HPE/Aruba switch side two interfaces:

interface 1/45
   untagged vlan 1
   trunk trk3 trunk

interface 1/46
   untagged vlan 1
   trunk trk3 trunk

and this on the PFSense:

If I connect Eth5 on one of that interfaces it works.
If i connect Eth4 also to the switches, it still works but as soon as I unplug Eth5 my connection to the PF is lost.

etherswtchcfg seems ok:

laggroup0:
	members 9,10
laggroup1:
	members 3,4,5

How is the trunk configured in the HP switch? It must be as load balancing as the 7100 on-board switch is.

Hi I've just created a normal trunk without LACP

trunk e 17/18 trk3 trunk

stephenw10

And there is no setting for failover, load-balance etc?

What happens if you connect Eth4 first in your current setup? Or just Eth3?

Do you get traffic over the first connected link that then fails when you disconnect it?

@stephenw10
Nope there is only an option if you wish an LACP Trunk or without LACP.
The Trunk and interfaces are always up on the switch and the PF.
But only one interface on the PF is working. Doesn't matter which one I connect first.

If i configure eth 3-5 on the PF in the same LAG, only port 5 is working.
If i configure eth 3-4 on the PF in the same LANG, only port 3 is working.
really strange.

If I ping the firewall i see on the packets counter that the traffic goes and comes from different interfaces in the LAG.

Hi all, do you know if the fix is now part of the current version 2.4.4p3? I'd like to configure something similar but I don't want to mess with the terminal. Thanks.

stephenw10

The fix allowing additional lagg groups to be added should be in p3 yes. If that's what you're referring to.

hi @stephenw10 , i'm very new to pfsense and negate so sorry if I ask you to repeat it, but starting from the default configuration could you explain to me how I should proceed to create a lagg between 4 ports of the internal switch? Just to give you the full picture, this is what I want to achieve:

ETH1 --> WAN

ETH2, ETH3, ETH4 --> not used for now

ETH5, ETH6, ETH7, ETH8 --> LAGG with interface OPT3

Can I do that with the UI?

Thank you.

stephenw10

You can do that but only using a load-balance type lagg. What ever you are connecting it to has to support that.

You can't access that as a different interface in pfSense. Traffic using that still has to be sent to the internal switch via lagg0.

You should start a different thread for this.

Steve

Do you mean I should manually type "1" in the LAGG column for the ports I want to join in a lagg? and that's it? Like you showed in this post:

@stephenw10 said in XG-7100 redundant connections to external switches:

You just have to add the ports to a new lagg group on the Ports tab i the switches config:

So here ports 7 and 8 are a lagg to another switch or another pfSense box carrying the LAN subnet.

Steve

stephenw10

Yes, if you want an additional lagg group of switch ports from the internal switch to some external device (that also support load-balance lagg).
