RIP: received v2 update from 10.0.0.1 on GigabitEthernet0/0 R1#RIP: received v2 update from 10.0.0.1 on GigabitEthernet0/0 To debug only RIP messages, we would run the following command: R1#debug ip rip To disable debugging of the ICMP events, simply re-enter the command with the no keyword in front of it: R1#no debug ip icmp In the output you can see that R1 has responded to the device with the IP address of 10.0.0.1 with two ping reply packets. In the example above you can see that I’ve enabled debugging only for the ICMP events (such as pings). You can choose to debug only specific events – for example, EIGRP information, received ICMP messages, etc.Ĭonsider the following example: R1#debug ip icmp It is meant to be used as a troubleshooting tool for only a short period of time. The debug operation takes a lot of CPU resources and should not be used often in production environments. The information are provided in real-time until the user disables debugging or the device is restarted. The debug command displays information about the Cisco device operations, generated or received traffic, and any error messages.
