2 - SNMP configuration
The Tekron NTP server provides status monitoring to Network Management systems
through the use of SNMP trap messages. The parameters that can be set are as follows:-
C
Community
The default value is “public”. This may be changed to suit the specific SNMP architecture
on the network if required. If SNMP is not implemented for other purposes on the
network, then the “public” setting allows the use of a simple SNMP trap display utility
running on a remote monitoring PC to display the status messages sent from the NTS.
SNMP Trap IP Address
This parameter allows for up to five destination IP addresses to be entered. Machines on
any or all of these IP addresses can then receive the status messages from the NTS unit.
Even if there is no formal SNMP system running on the network, the messages can be
received and displayed on the destination machines running “Windows NT” or higher
using the freeware utility “SNMPTRAP.EXE” which is on the CD supplied with the kit.
Syslog IP Addr
One or two IP addresses may be entered to define destination machines running system
logs. These parameters are really only useful in networks running full SNMP network
management systems. Similarly, the following S
Syslog facility code parameter is only
useful on full SNMP network systems.
Once configuration is complete, the set-up session may be terminated via option 9
9 Exit
and Save. The NTS will then reset and begin normal operation. (Note that the
“HyperTerm” response on the PC may well go “strange” as soon as the NTS resets. This
simply indicates that TCG 01 has reverted to normal operation on the serial port,
transmitting whatever output options are programmed via the TCG 01 configuration
program.)
D.5
Time Server Operation
The time-server’s operation is completely automatic once it is correctly configured for
the network. Time-server configuration info is retained indefinitely when the unit is not
powered (like all other TCG 01 configuration data). The time-server responds to time
requests from multiple clients using either SNTP or NTP protocol. If the option is
selected, the server will also broadcast time messages on a regular basis. The most
common protocol in use is SNTP. A sample SNTP client (freeware) for use on Windows-
based PC’s (prior to Windows XP) is included with each TCG 01 equipped with the NTS
option. Windows XP contains an NTP client as part of the operating system.
