Ensure that the route role and protocol are set
correctly. Route role must be set to
“standalone” and protocol must be set to
“none.”

Administrative

DNS name resolution is
incomplete.

To run the GUI, the

SA8220

resolve its own hostname via DNS, both
forward and reverse. The client machine on
which the browser is running must also be able
to resolve its own hostname using DNS, both
forward and reverse.

GUI Administrative
interface
initialization fails

DNS name resolution is
incomplete.

The client machine's host name must be DNS-
resolvable by the

SA8220

. If DNS is not used,

use the

config sys hosts add

command

at the CLI to add the client's hostname to the

SA8220

's local host file. The

SA8220

also

needs to be added to the client machine's local
hosts file. For Windows* NT*, the hosts file is
located in

c:\winnt\System32\drivers\etc

directory. For Solaris*, edit the

/etc/

nsswitch.conf

to allow for local

resolution. For UNIX*, the hosts file is located
in /etc. The format of the entry is:

<

SA8220

Name>
