How to mirror switch logs

[ksherwood]

Can anyone suggest how you would mirror the logs of your switch without turning on both TX and RX (so not to generate duplicate entries) ?

I am monitoring RX packets which doesn't include the local switch logs, which I want to capture also !

Ok, I have worked it out.

All you have to do is create two layer three interfaces (or switch virtual interfaces) and connect them together.

The RX monitor interface is one of them and the same interface is the set as the 'logging source interface'.

Make sure you turn off CDP on both interfaces.
