SM5310-T in SG3428X connected to 2.5G LAN port in ER7412-M2 does not pass data
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.
@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
