• Select naming to define the host name and domain name of the PDU:
– Host Name: After you configure a host name here and a domain name in the Domain Name
field, users can enter a host name in any field in the PDU interface (except e-mail addresses)
that accepts a domain name.
– Domain Name: You need to configure the domain name here only. In all other fields in the
PDU interface (except e-mail addresses) that accept domain names, the PDU adds this domain
name when only a host name is entered.
• To override all instances of the expansion of a specified host name by the addition of the
domain name, set the domain name field to its default, somedomain.com, or to
0.0.0.0.
• To override the expansion of a specific host name entry (or example, when defining a trap
receiver) include a trailing period. The PDU recognizes a host name with a trailing period
(such as mySnmpServer.) as if it were a fully qualified domain name and does not
append the domain name.
