Show log on Cisco 2950 / 2960 Series
Hello,
Actually I have some problem, I think my switch loose signal during some seconds (1 to10).
I have little cut connection on the computer linked to the switch.
How can I see the problem in the log.
The command show logging show nothing.

When I do
# show logging
I see log like this "2w3d ........" , always the same.
I think all event are not logged on the switch.
How can I check if it's OK, what is the command line to enable the log, what kind of log, and how can I see the log stored (for example all interface going down) ......

Login to enable mode then do this:
conf t
logging buffered debugging
This enables maximum logging to the buffer (show log). Ideally you would have a syslog server on the network and send these log messages to a server for historical purposes. The switch log space is limited.

Add this as well to make the timestamp a little easier to interpret:
conf t
service timestamps log datetime localtime

OK I will try tomorrow.
You talk about syslog server, how can I install this kind of server on my network.
Have you installation & configuration process and documentation ?
I think it will be very usefull to log my 40 cisco switchs.

Can we find a good syslog server on linux and which one ?
With the same kind of services (logs, graph, ...)

Linux has a built in syslog server I believe or you may have to install it. Check the man pages or linux forums for your distribution. Definitely not as simple as going the windows route unless you are a linux guru.
