NPort 5100A Series Web Console Configuration
translates this kind of text-based domain name into the numeric IP address used to establish a TCP/IP
connection.
In order to use the NPort 5100A’s DNS feature, you need to configure the DNS server. Doing so allows the
NPort 5100A to use a host’s domain name to access the host. The NPort 5100A provides DNS server 1 and DNS
server 2 configuration items to configure the IP address of the DNS server. DNS Server 2 is included for use
when DNS sever 1 is unavailable.
The NPort 5100A plays the role of DNS client, in the sense that the NPort 5100A will actively query the DNS
server for the IP address associated with a particular domain name. The NPort 5100A functions that support
domain name are Time server, Destination IP Address in TCP Client mode, Mail Server, SNMP trap
server, and Auto report to IP.
SNMP Settings
Community name
Setting Factory Default Necessity
1 to 39 characters public Optional
A community name is a plain-text password mechanism that is used to weakly authenticate queries to agents
of managed network devices.
Contact
Setting Factory Default Necessity
1 to 39 characters
(e.g., Support, 886-89191230 #300)
None Optional
The SNMP contact information usually includes an emergency contact name and telephone or pager number.
Location
Setting Factory Default Necessity
1 to 39 characters
(E.g., Floor 1, office 2)
None Optional
Specify the location string for SNMP agents such as NPort 5100A. This string is usually set to the street address
where the NPort 5100A is physically located.
IP Address Report
When NPort 5100A products are used in a dynamic IP environment, users must spend some time on IP
management tasks. For example, if the NPort 5100A works as a server (TCP or UDP), then the host, which acts
as a client, must know the IP address of the server. If the DHCP server assigns a new IP address to the NPort
5100A, the host must have some way of determining the NPort 5100A’s new IP address.
NPort 5100A products periodically report their IP address to the IP location server in case the dynamic IP has
changed. The parameters shown below are used to configure the Auto IP report function. There are two ways
to develop an “Auto IP report Server” to receive an NPort 5100A’s Auto IP report.
Use Device Server Administrator’s IP Address Report function.
“Auto IP report protocol”, which can automatically receive the Auto IP report on a regular basis, is also available
to help you develop your own software. Refer to Appendix E for the “Auto IP report protocol.”
