GS110EMX Link Aggregation with ASUS XT9
I’m trying to set up link aggregation on my GS110EMX to an ASUS XT9. I follow the instructions for the GS110EMX and the XT9. The process seems to work. The switch reports that the LAG is up. Traf...
cat /proc/net/bonding/bond0 shows both legs up on the partner device.
Looking at the General Log, I see the following line item just after plugging in the cables:
Bonding: Successfully.
I read an article that said to be sure the port speeds, duplex, MTU and Flow Control match on both sides on each port.
- I can verify the speed and duplex are 1000M-Full on each port and on each side.
- I’ve turned Flow Control on and off on the switch and get the same result.
- I can’t tell what the MTU is on the router. The switch lists the Max MTU at 10240, and it’s not configurable. I don’t know if this is an issue or not.

Is there any way to modify the Max MTU on a GS110EMX? I don’t see anywhere on the GUI to do it. Is there a CLI? I’ve not seen a way to SSL/TelNet into a GS110EMX.
Comparing notes with another user who has established LAG between a NetGear switch and an ASUS router, our configurations are nearly identical, except that his Max MTU is 9000 and mine is 10240. It may be a red herring as connectivity between my switch and my router is fine without LAG, and the MTU settings are the same. I’m not sure if LAG makes it more sensitive to MTU or if it has nothing to do with MTU.

None of this, ways out of scope for an unmanaged switch (what the GS110EMX is, or for the sake also the GS810EMX are).
The max MTU 10240 shown per port is the maximum frame size the GSx10EMX can handle.
