Using Ping/Tracert on an IP Network

Using Ping to Check Link Connectivity on an IPv4 or IPv6 Network

The ping operation monitors link connectivity and host reachability on a network. In a ping operation, the source sends an Internet Control Message Protocol (ICMP) Request message to the destination and the destination returns an ICMP Response message to the source.

Using Ping to Monitor the Reachability of Layer 3 Trunk Member Interfaces

A ping command can be run to test the reachability of trunk member interfaces, which helps you learn a physical link's status and locate faulty links.

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.

Using Tracert to Monitor the Forwarding Path on an IPv4 or IPv6 Network

The tracert command is used to monitor link connectivity and locate network faults.
