Hi,
after adding two copper cables in the SFP ports and a LAG on the 2 ports of the switch, it started crashing every few minutes. The instability occurred even with only one cable and I found that it does not occur in these two cases:
the LAG in question is used to join 2 switches, an old SG300 and this one, the other switch has no problems.

I upgraded to version 2.5.5.47 but the problem kept showing up; now I'm checking if the trivial deactivation of PnP is enough to no longer have problems ...
Any advice or idea about it?
Thanks,
Arturo.

- Since you tried latest firmware , guess you need to report this to Cisco :
