5.3  DNS CONFIGURATION 

DNS configuration affects the SNMP/Web adapter ability to resolve symbolic hostnames to IP 
addresses, and may impact other functionality (such as e-mail sending, for example): 
The SNMP/Web adapters can be configured to automatically obtain DNS server address (e.g. Primary 
and Secondary DNS server as specified in the DHCP response). This is the defaults setting. 
Alternatively, the IP address of the DNS servers may be specified manually. 
The adapters also offer a DNS lookup feature, which allows verification of the DNS setting by sending a 
DNS query. 

NOTE

: DNS settings may be critical for the SNMP/Web adapter operation. Incorrect DNS configuration 

may compromise the functionality of other network services (as an example, some services may require 
reverse DNS). Therefore make sure the DNS is correctly configured, especially when a manual 
configuration is selected. 
 
 
 

5.4  HOSTNAME 

The SNMP/Web adapter is configured with a 

hostname

: a fully qualified domain name for the adapter. 

The adapter will always include this information in the relevant communication to the DHCP server 
(option 12 – host name field). The DHCP server may use this information to update the DNS server, so 
that the adapter will be accessible using its domain name.  
The adapter can also be configured to use the hostname as received from the DHCP server. This is NOT 
the default behaviour and must be explicitly enabled through the console interface using the 

dhcphost

 

command.
