debug ip packet
command in the following example.
Field Description
s= Lists the source address of the packet and the name of the
interface (in parentheses) that received the packet.
d= 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.
len Displays the packet’s length.
sending, rcvd,
fragment, sending
broad/multicast
proto, unroutable The last part of each line lists the status of the packet.
TCP src= Displays the source and destination ports, the sequence
number, the acknowledgement number, and the window size of
the packets in that TCP packets.
UDP src= Displays the source and destination ports for the UDP packets.
ICMP type= Displays the ICMP type and code.
IP Fragment 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.
