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 
2. 
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.
