If there is no response to the broadcast Find WX message, the WX 
continues broadcasting the Find WX message for a period of time. If 
still no response is received, then the process skips to step 4 on page 
191.

3 If Items A and C are specified, the MAP sends a DNS request to resolve 

the fully qualified domain name of the WX switch. If the DNS server is not 
on the local subnet, the MAP uses the default gateway router address to 
contact the DNS server.

„

If there is no response from the DNS server, then the process skips to 
step 4 on page 191

„

If there is a response from the DNS server, then the MAP sends a Find 
WX message to the WX switch.

„

If a response is received from the WX switch, then the MAP sends 
a unicast message to the WX switch, to request an operational 
image.

„

If a response is not received from the WX switch, then the process 
skips to step 4 on page 191.

4 If the MAP cannot reach the WX switch using the static IP address 

information, then the MAP attempts to boot using the default boot 
process; that is, by contacting a DHCP server, as described in “How a 
Distributed MAP Contacts a WX Switch (DHCP-Obtained Address)” on 
page 190. If the default MAP boot process does not succeed, then the 
MAP again attempts to boot using its statically configured IP information. 
The MAP alternates between the two boot processes until the WX switch 
is contacted.

If the default MAP boot process is successful, but the DHCP response 
does not include a DNS server address, then the IP address of the DNS 
server specified as part of Item C is used.
