Appendix

234 AX3000 - User's Manual

Two DNS Servers:

1 - A DNS request is sent to the server 1.

2 - In event of no response from server 1, this request is sent to the server

3 - In event of no response from server 2, go back to step 1 (4 times max.).

4 - In event of negative answer from any server, the resolution is aborted.

5 - If other requests can be sent (using default DNS domains are defined),

go back to step 1.

Example: looking at the screen shots of the Chapter 3.1, these are the DNS

requests sent to resolve "as400" with 2 DNS servers and 2 default DNS

domains (of course this process is stopped if one DNS server sends back a

positive response):

- "as400.servers.axel.com" to DNS server 1

- "as400.servers.axel.com" to DNS server 2

- "as400.terminals.axel.com" to DNS server 1

- "as400.terminals.axel.com" to DNS server 2

- "as400" to DNS server 1

- "as400" to DNS server 2

c) Messages Displayed on the AX3000 Screen

To open a session the AX3000 must resolve the host name (if no IP address

has been associated through the set-up).

This is a screen-shot example when the resolution successes:

Connecting to as400.servers.axel.com:23 (Telnet)...

Session number 1

Resolving...

Resolved: 192.168.1.180

Connected

Explanation: the AX3000 attempts to resolve "as400.servers.axel.com". The

resolution process returns the IP address which is 192.168.1.180.
