Using Ping to Check the TCP Reachability on an IPv4 Network

The ping operation can be performed to check whether the client and the TCP server can communicate with each other and check the time taken to set up a TCP connection through three-way handshake.

Prerequisites

Before using the ping tcp command to check the time taken to set up a TCP connection on an IPv4 network, ensure that the TCP server is enabled on the peer end or the peer end is specified as the TCP server using the nqa server tcpconnect command.

Procedure

The time taken to set up a TCP connection on the IPv4 network is displayed.

For example:

<HUAWEI> ping tcp 10.1.1.1 3000
  PING TCP 10.1.1.1: 3000, press CTRL_C to break
    Reply from 10.1.1.1: Sequence=1 time=3 ms
    Reply from 10.1.1.1: Sequence=2 time=3 ms
    Reply from 10.1.1.1: Sequence=3 time=3 ms
    Reply from 10.1.1.1: Sequence=4 time=3 ms
    Reply from 10.1.1.1: Sequence=5 time=4 ms

    round-trip min/avg/max = 3/3/4 ms
