We currently have Cisco 3750's running Version 12.2(25)SED1. I have sysloging enabled to a specific syslog server.
If I receive a syslog alert from a specific switch and try to verify this by jumping onto the switch and checking for errors I dont see anything in the logs. I have tried to enable logging buffered level 7 but this does not show anything in the logs. I was rebooting a device that is connected to the switch. Surely it should an entry for the interface going down to a device if it was rebooted ?
You need the following per-interface config, in order to get syslog entry for interfaces going up/down:
logging event link-status
But, are you saying you find link status syslogs on the syslog server, yet not in the switch's logging buffer? Do you have the following configured?
! sends syslog to the switch logging buffer
logging buffered #### debugging
! sends syslog to pne or more syslog server(s)
logging trap debugging
