I'm trying to configure a SX3832 switch using Omada software controller v6.1.0.19.

Is it possible to have Jumbo Frames working on ports associated with a specific VLAN?

• I created a VLAN with no subnet, no gateway and no DHCP.
• I set this VLAN as the native VLAN for three ports on the SX3832, with no other VLAN allowed: all I want is those ports to act together as a pure L2 switch.
• No other ports on the switch are associated with this VLAN.
• In Devices > SX3832 > Manage Device > Config > General > Jumbo, I set a value of 9000.
• If I set all three computers NICs on those three ports to have a MTU of 1500, everything works fine, but I have no Jumbo frames (obviously).
• If I set all three computers NICs on those three ports to have a MTU of 9000, Jumbo ping tests time out (looks like the SX3832 is dropping them). But if I move all the computers to another physical, pure L2, unmanaged switch, Jumbo frames work perfectly.

Is it a bug on the SX3832, am I missing something or is it something the SX3832 can't do...?

Thanks.

Additional info:

• The SX3832 is connected to a ER8411 router; the trunk between the two of them does not allow the VLAN, but since the GUI would not allow me to not select at least one port on the ER8411 for the VLAN, I selected a port not connected to the switch. So, in principle, I figure the VLAN traffic should not reach the gateway and stay confined to the three ports on the switch that allow it.
