Speed limit at 100 mbs on LAGG

[Nico4526]

Hello,

I've have a pfsense cluster (v2.4.4p3).

I setup 2 interface in lagg (failover mode) to aruba switch
This port are 10 Gb/s speed capacity but there are running in 1 Gb/s capacity (ok in the switch status page)

On this lagg, we have created some vlan

In pfsense, for each vlan, and for the lagg0, i can see : autoselect mode

When i run a transfert beetwen vlan, i get only 100 Mb/s
I can see this speed in pfsense, and in my nagios

What's wrong please ?

Something else in that connection is probably linked at 100Mbps. Unless you actually have any traffic shaping running that is limiting it.
A lagg like that in any mode should pass at least 1Gbps. A assume it's LACP though?

Thanks for your answer.

All port on the swith are at 1 Gb/s mode. No traffice shapping. The lagg is on failover mode.

I try to avoid assumptions, so I'll just throw it out there... are your transfers getting 100 Mb/s or 100 MB/s? Because 100 MB/s would be gigabit.

[stephenw10]

And the hosts you're sending data between are connected directly to that switch?

[Nico4526]

Yes it's really 100 Mb/s (and not MB/s)

And yes, all host are connected to the same switch

What does Aruba have to say?

If you are getting 100mbit/sec it is probably because something in the path is a 100Mbit connection.

100 mb/sec is really slow!

something in the path is a 100Mbit connection.

A bad Ethernet cable can cause that.

[marvosa]

Agreed. Something in the path between the two endpoints is slowing the traffic down. If you're seeing a hard 100 Mbit limit on file transfers, then it's most likely a misconfigured port, a hardware limitation on some device in the path or a bad cable(s). So, you'll need to assess the config and connection state for every physical connection along the path to each endpoint, including the NIC's at each end. Then start looking at cabling.

[Nico4526]

the cables are new and the switch is in full duplex 1 gb / s for all connexion of the lagg.

I will try to change cables again

That doesn't mean you didn't get a bad one. That does happen occasionally. Also, are the cables direct between devices? Or do you go through other cables connectors, etc.. There was someone here a while ago, who discovered he had a bad connection in the installed wiring.

Also, you can get inexpensive cable testers that do a basic continuity test. They can identify cable problems.
