• Trouble ticket generation
• The Digivance CXD/NXD system outputs a wealth of raw event information. It is up to
the NMS to determine what alarms are generated, and how to dispatch resources to rectify
the situation.
• E-mail, pager, and cell phone notification methods are recommended for a user-defined
subset of fault conditions.
• Scheduling tables are a plus for those operators who are not on call 24 hours a day.
3.7 Configuring the Hubmaster Node
A correctly configured Hubmaster Node is required to operate a Digivance CXD/NXD network.
To simplify this task, the Digivance CXD/NXD system software includes the configure-
hubmaster script. The use of this script is described in Section 10.1. In addition to the common
node tasks throughout this document, the Hubmaster has the following responsibilities:
• Network Timing Protocol Daemon (/usr/sbin/ntpd), synchronous with GPS input.
• Dynamic Host Configuration Protocol (DHCP) server (/usr/sbin/dhcpd3).
• Domain Name Server (/usr/sbin/named).
• Node IP Receiver/Sender (/usr/sbin/niprs) server-side properties discussed in Section 9.2.
• Digivance CXD/NXD Tenant processing (/usr/bin/tenantscan and /usr/bin/tenant).
3.7.1 Using the Configure-Hubmaster Script
Use the following procedure to invoke the configure-hubmaster script:
1. Login locally to the target node as operator
2. Type “sudo /usr/sbin/configure-hubmaster” and enter the password when prompted.
3. Enter the information as shown in the following paragraphs.
3.7.1.1 IP Address / Netmask
At the IP prompt, enter the static IP address that has been assigned to this Hubmaster node. This
is a crucial step, as it not only defines the node’s identity, but, in conjunction with the netmask
input, it also defines the subnet it services. It is advised that the node IP be in the form
XXX.YYY.ZZZ.1, to match the default Digivance CXD/NXD DHCP settings. The netmask
prompt further defines which subnet the Hubmaster node will service. The default is
255.255.255.0, or a “class C netmask”. This is the recommended netmask value for the
Digivance CXD/NXD system.
Note: The CXD/NXD Element Manager System (EMS) may be used to control and monitor
the system.
