ANAGEMENT
You can configure up to 50 IP addresses by using the command repeatedly.
The is used for testing the gateways passed by the packets from the source
tracert
host to the destination one. It is mainly used for checking if the network is connected
and analyzing where the fault occurs in the network.
The execution process of
value as 1 and the first hop sends back an ICMP error message indicating that the
packet cannot be sent, for the TTL is timeout. Re-send the packet with TTL value as 2
and the second hop returns the TTL timeout message. The process is carried over and
over until the packet reaches the destination. The purpose to carry out the process is
to record the source address of each ICMP TTL timeout message, so as to provide the
route of an IP packet to the destination.
Perform the following operation in all views.
