LAG with SFP+ not working
I have 2 switches (XS512EM and XS724EM) each with 2 AXM761 SFP+ modules and would like to connect them via LAG. The LAG works with copper cables, it does not work with fiber (OM3, 3m for testing). The ports themselves are active and up with 10G. With a static configuration, the LAG is also displayed up, but constantly shows dropouts, e.g. on pings. As a LACP, it stays down. The firmware version on both devices is 1.0.2.5, after the firmware update the factory settings were reset again. As a normal uplink without LAG, one fiber connection works without any problems on both SFP+ ports. Nothing else was configured on the switches and nothing else was connected. Thanks for any suggestions.

- Hallo Matze,
Haven't mixed by accident the port 23T/24T with the port 23F/24F? Some older product description translations are misleading - talking of dedicated instead of combo ports, eg. German

24x Multi-Gigabit Plus-Switch mit 10G Ports und 2 dedizierten SFP+-PortsHmm, not sure what you mean? Nothing else is connected to the switches (only one port for administration), the rj45 combo ports are free. the LAG members are those who came as linked in the port overview.

OK - this was the only question I had.
Afraid, just another user here, and I have no other XSxxxEM at hand for set-up a SFP+ based LAG configuration. Based on your description, it looks like your XS724EM does not bring up a LACP LAG configured on both ends to the very similar XS512EM using the SFP+ ports. Similar to your other test, I can confirm the XS724EM does establish an LACP LAG to other switches (XS748T here) using two copper Ethernet links.
