Does anybody know the cause of an unexpected reboot with no crash information in flash, I have a WS-C3560X-48T-L Switch with c3560e-universalk9-mz.150-1.SE.bin image.


Is an action recommended?

If you do not need features

If you do not need features found in 15.0 then I recommend you downgrade your IOS to 12.2(55)SE9.


If you need features in 15.0 then I recommend you upgrade your IOS to 15.0(2)SE4.

Just be mindful that 15.0(2

Just be mindful that 15.0(2)SE4 and earlier are impacted by a number of security bugs - see .

You may find 15.0(2)SE6 is marginally more stable as it has a few more bug fixes as well.  No new features were added between SE4 and SE6.
