Saturday
Model: TL-SM5310-T   SG3428X   ER7412-M2  
Hardware Version:
Firmware Version:

Environment:
Omada OC200 v1.40.18 Build 20260506 Rel.74003

Gateway: ER7412-M2 v1.30 1.1.1 Build 20251112 Rel.54883

Switch: SG3428X v1.30 1.30.19 Build 20260310 Rel.11233

SFP+ installed in SFP+ socket of SG3428X: SM5310-T, connected via 3m long Cat6A cable

Flow control enabled on both 2.5G Ethernet in gateway and SFP in switch

 

Issue is that only management data is being passed.  The switch adopts perfectly and is fully manageable and visible.

 

2.5G port set to auto/auto speed, Native VLAN set to Default(1), flow control enabled

 

SFP+ port in switch set to 10G/Full duplex, Native network is Default(1), Network Tags set to Allow All, Operation=switching, Flow control enabled

 

Maybe I'm just missing something but there is nothing that I can do to allow any device connected to the switch to communicate through the gateway using this setup.

 

If I change to using a 1GE port on the switch then all is ok, so has to be something to do with the SFP+ module or config.  I've tried different cables and moved the SFP+ module into other slots too.

All suggestions greatly appreciated.

Hi  @thmark 

 

Thanks for posting here.

Is your installation as below?

 ER7412-M2 <2.5G RJ45port>---SM5310-T---<SFP+ port>SG3428X

 

Where is the OC200 plugged in? Is it the switch SG3428X?

 

but there is nothing that I can do to allow any device connected to the switch to communicate through the gateway using this setup.

>>>Does this mean, all clients plugged into the switch SG3428X have no Internet access? Can they obtain valid IP address from the gateway?

 

SFP+ port in switch set to 10G/Full duplex, Native network is Default(1), Network Tags set to Allow All, Operation=switching, Flow control enabled

>>>Is it possible to change the speed to 2.5G? please share us with a screenshot.

 

In the meantime, please disable the Flow Control for the ER7412-M2 port and see if it helps. Thanks.

Wish you a happy life and smooth network usage!  >Get the Latest Omada SDN Controller Releases Here< >Get the Latest Firmware Releases for Omada Routers Here< >Experience the Latest Omada EAP Firmware<

  @Vincent-TP , thank you for your message
OC200 is connected to ER7412-M2 port 4

You can see ER7412-M2 is showing port 2 at 2.5G

 

 

Now flow control on ER7412-M2 port 2 has been disabled but did not change anything

 

SFP+ port on SG3428X only allows selecting between 1G and 10G (no 2.5G option)

 

I appreciate your help with this and am willing to try anything to oversome this hurdle.  Thank you very much
