This volume argues that East Asian countries have far from exhausted their growth potential. If this ping succeeds, it is an indication that there is no routing problem. CLI commands. IPv6 Ping. Since these datagrams try to access an invalid port (Default 33434) at the destination host, the host responds with ICMP "port unreachable" messages that indicate an unreachable port. This is the time required to send an echo packet, and get an answer back. When moving between interfaces, the switch retains the current privilege level (Manager or Operator). Changing parameter settings. Be sure to accept the key. If it has to reply to a packet coming from this network, it does not know how to handle it. You type in configuration commands and use show commands to get the output from the router or switch. The purpose behind the traceroute command is to record the source of each ICMP "time exceeded" message in order to provide a trace of the path the packet took to reach the destination. A destination unreachable error PDU was received. The ping is successful only if: the destination is able to get an echo … First, three datagrams are sent, each with a TTL field value set to 1.
