Fn-221 - later models - Network Bond Fail? (Tos6)

[Gremlin]

I have 2 x 221 models which have now both been updated to TOS6.0.648.
In process of updating nas & network, both nas have revealed that LAN1 nic is capable of 2.5Gbe connections (Having added 2.5Gbe switches at same time). viewtopic.php?p=43705#p43705
However, LAN2 nic is 'stuck' at 1Gbe.
When I attempt to set up bond as Balance-ALB (ie no setup on switch), the connection is set with bandwdith as 3.5Gbe (according to nas). However, this bond will eventually FAIL. Using fixed IP and this can lead to state of confusion with the Bond ip sometimes allocated to BOTH nic!
I have tried using dynamic bond (LACP), since my switches will allow that, but seem to limit connection to 1Gbe bandwidth (according to NAS)

My current understanding is that bonded connections must have the same connection speed on all links so the asymmetric nature of these *-221 models will not allow bonds to function correctly.

I am currently testing the 'active backup' settings which (so far, but only minutes in testing) is showing the full speed of the lan1 nic (2.5Gbe). This way I can at least see the benefit of the 2.5 speed and switches.

Any comment/thoughts would be appreciated.

Same problem, I tried to restore the system but it hangs and won't work!

That may actually be a different problem. Restoring the same tos version is, in my experience (lots!) relatively painless. BUT, only have Lan1 connected when you do it. {Just a thought - Been there }

Your understanding is correct—bonding requires matching NIC speeds. Balance-ALB fails due to asymmetry; LACP caps at 1Gbe. Active-backup is the workaround for 2.5Gbe. Consider disabling LAN2 if unused. muft rashan program 2024 online registration

Rather than disable LAN2, I have chosen to use the LAN2 IP for accessing nas desktop, leaving LAN1 available for "unimpeded" transfers. I hate waste

Hello, Gremlin, thank you for your spirit of exploration. If you have any insights, feel free to share them with everyone.

The problem with LAN2 on two TerraMaster x221 NAS after upgrading to TOS 6.0.648, yet LAN1 works well at 2.5GbE speed, is really concerning. LAN2 may be connected via CAT5e cable (which only supports 1Gbps) or the cable is defective. Use a CAT6/6A cable (the same as LAN1). Try connecting LAN2 to another 2.5GbE port on the switch to rule out a port problem.

Frankley, that's a load of rubbish. Apart from the fact it has already been accepted that LAN1 & LAN2 on affected models do operate at different speeds, In this case the category of cable is irrelevant. In my case I already have two (pre-installed) cat5e cables running from house to office (about 25m each) on a 2.5Gbe bond quite happily plus I have another existing cat5e cable running between floors of the house (outside as well) that is running a 10Gbe link between switches. Not ideal, but the distances are relatively short. All self-installed, so I know the connections are good!

You sound like an ISP drone that, as soon a something goes wrong, blames the cables.
