Re: CPU 98% and disconnecting the telnet

IP input process is eating up most of the CPU resources. The link below should help in troubleshooting the cause of high IP input process:

http://www.cisco.com/en/US/products/sw/iosswrel/ps1828/products_tech_note09186a00800a70f2.shtml#ip_input

Also, it is recommended to perform troubleshooting through the console.
