domains serially will achieve the desired result (i.e. Digivance CXD, Digivance CXD-4XD-
G22, etc.).
10.1.5 DNS Forwarding
The script will prompt “Enter a list of upstream DNS servers, one per line: (control-d when
done)” to set up DNS forwarding. It is expecting as input the IP address of each Domain Name
Server that the Hubmaster node can connect to. If there are no upstream DNS servers, leave
this entry blank. Hit CNTRL-D when finished entering DNS upstream servers.
Note: It is advisable to reboot the Hubmaster node once the script has been run to ensure that
the modifications made via configure-hubmaster are in effect.
10.1.6 NTP Service
The script will prompt "Enter a list of NTP servers, one per line: (control-d when done)" to set
up NTP services, which will allow the data/time to be pushed to this domain from the
configured servers. If none are specified, then the Hubmaster will use its current time as the
default.
10.1.7 SNMP Trap Sinks
The script will prompt "Enter a list of SNMP v1 trap-sinks, one per line: (control-d when
done)" in order to set up any SNMP-V1 trap receivers that traps should be transmitted to. The
script will then prompt "Enter a list of SNMP v2 trap-sinks, one per line: (control-d when
done)" in order to set up any SNMP-V2 trap receivers that traps should be transmitted to.
Any number of trap-sinks can be configured, though the quantity should be kept to a minimum
in order to minimize processor load on network nodes. Also, SNMP V1 and V2 trap-sinks can
configured simultaneously within the same domain. In the event that SNMP-V1 trap-sinks are
configured, the Digivance software will convert the SNMP-V2 traps to SNMP-V1 traps before
transmitting them.
10.2 Using Dynamic Host Configuration Protocol with Digivance CXD
All Hub and RAN nodes, except the Hubmaster node, utilize DHCP to obtain their IP
addresses. Each Digivance CXD Hubmaster comes standard with a DHCP server to configure
its subnet. The following sections explain its use.
10.2.1 Using The Provided Hubmaster DHCP
The Digivance CXD Hubmaster node comes standard with DHCP already activated. When
employing multiple Hubmaster nodes, it is important to run the configure-hubmaster script as
outlined in Section 10.1 to prevent collisions.
