The common symptoms for us are alarms of TM errors / resets. We’ve
been told on multiple TAC cases that logs indicating transmit TM
errors are likely caused by problems in one of the SFM links / lanes.

So don’t errors like this suggest replacing the hardware?

Hey,
this sounds like a good tip. We are seeing a issue very similar to the one
reported in this thread.
Speed to local servers is fine, but to remote servers the speed decreases
depending on the latency to them (while having no overloaded links or
something like that).
In our case the core
The FLS switches do something weird with packets. I've noticed they
somehow interfere with changing the MSS window size dynamically,
resulting in destinations further away having very poor speed results
compared to destinations close by.
We got rid of those a while ago.

We are having a strange issue on our MLX running code 5.6.00c. We are

We use the MLX to handle both external BGP and internal VLAN routing. Each
FLS648 is used for Layer 2 VLANs only.
