MARTNA™ 10G NETWORK ACCESS (SMARTNA-X)
TROUBLESHOOTING | TROUBLESHOOTING CONNECTIONS TO SMARTNA-X

Serial port and reset IPv4 access locally. See the “Logging in to the CLI locally” section on page 23 for details on
how to log in via Console.
To find your SmartNA-X IPv6 address, ping the network IPv6 link-local address (ff02::1) to return the link-local
address of all connected devices. The link local address of Network Critical devices always contain 1d:ffff:fe. If
multiple Network Critical devices are connected to the network, pinging the target device connected then
disconnected will easily reveal the correct device, as demonstrated below. The relevant ping commands for Linux
and Windows are as follows:
Linux – ping6 ff02::1%interface
Windows – ping6 ff02::1%interface
where interface is the local Ethernet interface, as identified by the interface configuration command ifconfig (or
the equivalent on your operating system).
When you have the correct link-local IPv6 address, use it to connect to the management interface and reset the
IPv4 address—suitable commands and example output are provided below:
You will now be able to access SmartNA-X using the reset IPv4 address:
