I am not clear from your post whether your syslog server receives some messages but not level 2 or whether it does not receive any messages. Understanding this difference will be very important in understanding your problem and finding a solution. Perhaps you can clarify?
It would also be helpful if you would post the part of the config dealing with logging, post the first 20 or so lines of show logg on the 3550, and post the output of a ping from the 3550 to the syslog server.
Thanks for replying me rick , well the problem is I m not getting only critical events on my syslog server from 3550 switch e.g messages like interface up or interface down messages are not showing up on server while I m getting other messages on syslog server , my configurations are minimal for syslog :
logging trap 2 (for critical events)
logging facility syslog
these are my configs but I m not getting these traps on my server .
I believe the messgae which you are expecting is link up and down messages to be sent to syslog server are not critical message but are error message so try setting the trap level to 3 instead of trap 2 and see if that resolves your issue
I believe you are expecting some messages like this
LINK-3-UPDOWN: Interface Port-channel1, changed state to up
to be sent to syslog server.So the trap level should be set to 3.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
