High CPU due to Interface Tunnel

Hi All,


Few days ago I was facing High CPU on my 3945 router. and when I checked the router log, i found the interface tunnel log as below :

 

Jun 26 17:55:58.775: %LINEPROTO-5-UPDOWN: Line protocol on Interface Tunnel0, changed state to  up Jun 26 18:11:43.860: %LINEPROTO-5-UPDOWN: Line protocol on Interface Tunnel0, changed state to  up Jun 26 18:27:28.904: %LINEPROTO-5-UPDOWN: Line protocol on Interface Tunnel0, changed state to  up Jun 26 18:43:13.964: %LINEPROTO-5-UPDOWN: Line protocol on Interface Tunnel0, changed state to  up Jun 26 18:58:59.029: %LINEPROTO-5-UPDOWN: Line protocol on Interface Tunnel0, changed state to  up Jun 26 19:10:26.785: %SYS-5-CONFIG_I: Configured from console by tan_h on vty0 (159.163.148.163)

There is no interface tunnel configured in this router but why the interface tunnel log came to this router?

 

Thanks for your help.

Hi,

These log messages do not necessarily mean high CPU.

Do you have Multicast routing or WCCP configured on this router?
