SX3008F Port Behavior
Hello,
recently I got the SX3008F in addition to my T1700G-28TQ because I needed a few more SFP+ ports. But the port behavior of the SX3008F is strange, at least to me.
On Server one, when the link goes does down, due to a server restart or whatsoever, the port/link on the switch never comes back up again, I need to restart the switch or fiddle with the settings like port disabled/enabled.
1 2024-09-29 01:01:28 DDM level_6 Port 2 SFP Module rx power is lower than warning point. 2 2024-09-29 01:01:28 DDM level_6 Port 2 SFP Module rx power is lower than alarm point. 3 2024-09-29 01:01:27 Port level_5 The 1000_BASE_SX_SFP Transceiver is inserted , change speed of port Te1/0/2 to be 1000M. 4 2024-09-29 01:01:26 Link Scan level_5 Te1/0/2 changed state to down.
On server two, when the link goes down, it comes up again but will only be 1G, if I force it on the server to 10G via ethtool the port will go down again. If i restart the switch the port will be at 10G again until it gets down again due to a restart etc.
I never had this happen with the T1700G-28TQ.
Hey Clive,
thanks for your response. To be honest, I don't see how your request is helpful to the problem because as I stated, before the addition of the SX3008F, everything was fine, and these symptoms never occurred with the T1700G-28TQ.
But anyways, I created a ruff network diagram:
In this Diagram SVR0 is the one where the port after a restart never comes back up again and SVR2 is where it only settles at 1G until a restart of the switch. On SVR1 I did not detect any strange behavior (for now).
All fiber connections are 10G.

The NIC of SVR0 is a Supermicro AOC-STGN-i2S with an HP SFP+ module (PLRXPLSCS433H).

The NIC of SVR2 is an Intel X520-2 with an Intel SFP+ module (FTLX8571D3BCVIT1).
For completion, the NIC on SVR1 is an HP NC552SFP Dual Port 10GbE Server Adapter, because the server is running Windows Server, I cannot get any further information, but I believe the SFP module is an Intel (FTLX8571D3BCVIT1).
What I tested so far:
- Swapping the cable to a brand new one
- Swapping the SFP+ modules around
- Testing a brand new SFP module
So far, I don’t know what is wrong, but the only change to the network is: Removed the SFP modules from the T1700G and plugged them into to SX3008F.
