Command Reference
debugging ip
Purpose Using debugging ip icmp command to enable the ICMP debugging.
Use the undo debugging ip icmp command to disable the ICMP debugging.
The debugging ip packet command is used to enable the IP packet debugging.
The filtration to the debugging information can be accomplished by filtering the IP
packets via acl.
Use the undo debugging ip packet command to disable the IP packet
debugging.
Syntax debugging ip { icmp | packet [ acl { acl-number1 | acl-number2 } ] }
undo debugging ip { icmp | packet }
Parameters acl-number1
ACL based on the interface. Valid values are 1000 to
1999.
acl-number2
ACL. Valid values are 2000 to 3999. The ACL in the
value range of 2000 to 2999 is the basic ACL. The ACL
in the value range of 3000 to 3999 is the advanced
ACL.
Example Enable the IP debugging.
