The SNMP/XL agent uses the Name Service Routines to resolve
node names into IP addresses. These routines are used for node names
that appear in the SNMPCONF file and node names that are specified
in the snmp commands (for example, SNMPGET, SNMPNEXT, SNMPSET, SNMPTRAP, and SNMPWALK).
The Name Service Routines use the following two methods of
resolving node names into IP addresses:
The file RESLVCNF.NET.SYS is checked to determine if a node in the network
is acting as the domain name server. If a node is listed in this
file, a domain name request is sent to that node to resolve the name
into an IP address. If the request fails or the file does not exist, the
following method is used.
The host database, located in the file HOSTS.NET.SYS is checked. This flat-ascii file contains entries
for all of the hosts in the company network. An example of an entry
is:
192.1.27.63 mpenode mpenode.cup.hp.com
When this method is used, the Name Service Routine sequentially searches
the host database for the node name, and if found, returns the proper
IP address.
If both methods fail, the subsystem is not able to generate
an IP address for the node name.
