What are you doing to try and generate a logging event?

but it should be logging SOMETHING, and I see nothing at all.

example:  i have a dell switch at one site that was apparently blocking a tcp\ip time clock.

clock worked fine in main office on HP switch, moved it to another plant that has dell switch, no connectivity.  tried different ports, nothing.  moved it to another switch (HP) and it worked.

so then I put a cheap, non-managed switch in between the dell switch and the time clock, and time clock started working.

BUT - no logs, nothing in the logs at all as to why the clock appeared to be blocked.

I now have several users at a different plant who keep dropping their network connections, but there is nothing whatsoever being logged by the dell switch at that site.

I should see something.... I did with procurve, but apparently not with dell.  how do I troubleshoot network issues when the switch does not log a single thing?

surely it is something I have not configured correctly, I need to see logs to do my job.

I was just speaking with my boss, and he says we have to turn on the ports for the switch to log errors, that it does not log errors on all ports automatically, is that true?

if so, can you point me to how to turn on logging for all ports?

I also found this in the N-Series UG under Default Log Settings, by default, no messages are sent to the log file that is stored in flash, and no remote log servers are defined.  From Privileged EXEC mode, use the following commands to configure logging to the local flash, if that is the desire.

logging file [severity*]

*Table 11-1 in UG

Hope this helps,
