Usage
To stop packets from flooding the user terminal when debugging is turned on, use
Information
the count option.
IPv4 Routing
Description
Lists the destination address of the packet and the name of
the interface (in parentheses) through which the packet is
being sent out on the network.
Displays the packet's length.
The last part of each line lists the status of the packet.
Displays the source and destination ports, the sequence
number, the acknowledgement number, and the window
size of the packets in that TCP packets.
Displays the source and destination ports for the UDP
packets.
Displays the ICMP type and code.
States that it is a fragment and displays the unique number
identifying the fragment (Ident) and the offset (in 8-byte
units) of this fragment (fragment offset) from the beginning
of the original datagram.
