debugging tcp event
Parameter
acl-number1: ACL based on the interface, in the range of 1000 to 1999.
acl-number2: ACL in the range of 1 to 199. The ACL in the range of 1 to 99 is
the basic ACL and that in the range of 100 to 199 is the advanced ACL.
Description
Using debugging ip icmp command, you can enable the ICMP debugging. Using
the undo debugging ip icmp command, you can 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. Using the undo debugging ip packet command, you can disable
the IP packet debugging.
Example
Enable the IP debugging.
