d.
If the ping is successful, then that network switch is most likely configured for IPv6. Retry this
same test on the next level switch if possible, all the way to the 1GbE switch until you are able to
find the point in the network IPv6 is disabled or blocked.
e.
Ensure you remove the ipv6 link-local address on the switch if the network administrators do not
want it enabled.

Test IPv6 connectivity to VMware ESXi hosts
To test IPv6 connectivity to each VMware ESXi node, perform the following from the management VM.
1.
Open a web browser to the iLO of the first HC380 node and log in. Use either a username and
password combination you previously set up on the iLO or the Administrator user with the password
on the Toe Tag on the HC380 node.
2.
Once logged in, open a remote console to the system. Accept any security warnings that appear.
3.
Press Alt + F1 at the same time and log into the esxcli command interface with the username root
and password HyperConv!234.
4.
Execute the following command and record the entry for vmk3:
root@node1:~] esxcli network ip interface ipv6 address list

From the Management VM, open the Start menu and open Command Prompt.
6.
Type the following command, replacing <<esxi_ipv6_address>> with the Link Local IPv6 Address
you obtained from step 4.
It is normal for the first couple ping attempts to result in "Destination host unreachable" as the system
is still trying to discover the Link-Local IPV6 address of the iLO
