Traffic transiting the router will not be logged without "debug ip packet", and also not logged unless you disable CEF and fast switching on the interface that is processing traffic. This will make your router about 100 times slower.
i.e interface FastEthernet0/1 no ip route-cache cef no ip route-cache Then check the IP parameters: ROUTER#sh ip interface fa0/1 FastEthernet0/1 is up, line protocol is up ...... IP fast switching is disabled IP fast switching on the same interface is disabled IP Flow switching is disabled IP CEF switching is disabled IP Fast switching turbo vector IP multicast fast switching is disabled ..... -----Original Message----- From: cisco-nsp [mailto:[email protected]] On Behalf Of Karsten Thomann Sent: 12 May 2015 23:18 To: [email protected] Subject: Re: [c-nsp] Logs are empty Have you tried to use "logging buffered 128000 debugging"?
