4.6.1 Task 1: Verify ping Functionality

Verify the functionality of the ping command before any changes using the following commands. By verifying the ping command before any changes, you know what is the results should be after changing the interfaces. Similar commands can be used to check other servers that connect to Oracle Exadata Database Machine.

# grep "^nameserver" /etc/resolv.conf
nameserver ip_address_1
nameserver ip_address_2

# ping -c 2 ip_address_1
PING ip_address_1 (ip_address_1) 56(84) bytes of data.
64 bytes from ip_address_1: icmp_seq=1 ttl=57 time=1.12 ms
64 bytes from ip_address_1: icmp_seq=2 ttl=57 time=1.05 ms
 
--- ip_address_1 ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 1002ms
rtt min/avg/max/mdev = 1.054/1.087/1.120/0.033 ms

If the test is not successful, showing 100% packet loss, then you should expect similar results when this same verification is run in "Task 4: Verify the 10 GbE Interfaces". If the test is successful, showing 0% packet loss, then you must see similar results after changing the 10 GbE connections.
