4.2.4 Management using SNMP
The UPSLink can be managed through the SNMP protocol using NMS (Network Management
System) or SNMP Browser. Before using the NMS or SNMP Browser, the user must set the access
control configuration properly so that the UPSLink permits access from hosts where the NMS or
SNMP Browser is running.
4.3 Dynamic DNS configuration
When users connect the UPSLink to a DSL line or use a DHCP configuration, the IP address might be
changed whenever it reconnects to the network. So, IP based transactions could be troublesome in
this case. For example, if the administrator only has remote accessibility, there is no way to recognize
if an IP address has changed, or what the new IP address is.
A Dynamic DNS service is provided by various ISPs or organizations to deal with the above issue. By
using the Dynamic DNS service, users can access the UPSLink through the hostname registered in
the Dynamic DNS Server regardless of any IP address change.
By default, the UPSLink only supports Dynamic DNS service offered at Dynamic DNS Network
Services, LLC (www.dyndns.org). Contact Sena technical support for issues regarding other Dynamic
DNS service providers.
