Testing Network Connectivity
To make sure your network connections are configured and behaving properly, do these tasks:
•
Confirm that your computer has the appropriate settings for DNS servers, the correct
hostname, and an available IP address with the proper subnet mask (show hosts); the
proper default gateway (show ip default-gateway).
•
Check network interfaces (show interfaces). Make sure the links are up, the addresses
are correct, default routes are set correctly (show ip route). Check cable connectivity.
•
Check ARP tables (show arp).
•
Check DNS /hostnames configurations (show hosts).
•
Check that applications like SSH, and Firefox are working.
•
Test connections to remote servers; use ping (Ctrl+c to stop ping):
a. Ping the loopback address (by using the ping 127.0.0.1 command) to verify that TCP/
IP is installed and working correctly on the local computer.
b. Ping the local computer IP address to verify it was added to the network correctly.
c. Ping the IP address of the default gateway to verify that the gateway is functional and
it is possible to connect to a local host on the local network.
d. Ping the IP address of another remote host to verify that you can communicate
through a router.
