Command
Debug IP Packet
Use
This command enables IP packet debugging messages. The debugging shows all IP information being processed by the router. You can also use an access-list to limit the debug output.
Syntax
Router#debug ip packet
OR
Router#debug ip packet <access-list>
Example
In the below example, we enable IP packet debugging on R2.
R2#debug ip packet |
Here we use an access-list to filter the debug output.
R2(config)#access-list 155 permit icmp any any |
