Syslog Question

tom.taylor

Level 1

I am capturing syslog events from numerous cisco switches and have noticed my 2950 switches generate link up/down as errors when a connected device is rebooted. I obviously need to collect all error level events from these switches but do not really consider these link up/down messages as being at the error level. Is there any way to change these events from being considered errors to being considered informational events?

You can change the logging level on the switch. You should have a statement like:

logging trap critical

There are seven levels:

0 emergencies

1 alerts

2 critical

3 errors

4 warnings

5 notifications

6 debugging

Tom's original post specified that he wants to continue to collect all error level messages except for the link up/down messages. Changing the logging level would prevent that.

Try configuring no logging event link-status.

I agree that no logging event link-status default works on my layer three switches, for sure on my 6509 as that command is already there. However, on my layer two 2950's this command does not exist. I have looked around and can find no way to turn link up/down messages off. Can they be turned off?

I do not know if it is a version difference, feature set difference, or what, but it works fine on my 2950.
