1.1.1 GPS Synchronization ............................................................................................... 1.1-2 Chapter 1. Description and Start-Up
This document describes both the technical and functional characteristics of GPS Sync and
GPS NTP, a substation hardened Synchronizer and Reference Clock system. The
Synchronizer distributes the Reference Clock signal to synchronize equipments (The GPS
is an electronic device that provides accurate time information to all equipments that are
“connected” to it).
The GPS is available with the Reference Clock and the Synchronizer in a single enclosure,
or as separated units.
-
GPS Sync: has synchronization analog IRIG-B channels, digital and serial.
GPS NTP: NTP (Network Time Protocol) is the most used protocol for synchronizing
the clocks of computer systems over packet-switched, variable-latency data networks.
1GPS NTP synchronizer uses the GPS satellite system as a stratum 0 NTP server to
synchronize itself, and then works as a stratum1 NTP server.
1.1.1
GPS Synchronization
The distributed nature of electronic equipment in power systems adds complexity when
analyzing system wide events. Precise time accuracy, distributed throughout the network, is
critical for system synchronization and providing useful sequence of event data for proper
analysis.
The key element in synchronization is a Reference Clock. These are electronic clocks
synchronized with a common time reference, such as the signals provided by the GPS satellite
system. Substations in electric power systems contain digital equipment that monitors and
protects the physical infrastructure of the electrical grid. Disturbances to the network commonly
affect multiple substations. A common time reference at each substation is critical to effectively
utilize the data recorded by the digital equipment for post event analysis.

1.2.1
Power Supply
3 terminal block screw cage type connector (5.08 mm pitch).
There are two different power supply options:
-
Isolated multirange AC/DC (60-260VAC and 60-360VDC
Isolated multirange DC (16-75VDC
1.2.2
SRV: Service Port
RS232 port – DCE configuration. The front SRV service port has a fixed configuration.
-
GPS Sync: 9600 bps, 8N1, and no flow control.
GPS NTP: 115200bps, 8N1 and no flow control.
1.2.3
GPS Sync
1.2.3.a
Synchronization Bus Connector
The Synchronization Bus Connector consists of an 8 terminal green screw cage type connector
(5.08 mm pitch) for connecting to the Reference Clock and other GPS Sync units without GPS
Clocks.
The synchronization bus is isolated (2.000 V, 1 min).
1.2.3.b
Out of Lock
The Out of Lock connector consists of a 3 terminal green screw cage type connector (5.08 mm
pitch). The output contact is closed when the Reference Clock does not fulfill the preestablished precision criteria.
When locked to the GPS satellite constellation, the Out of Lock is not set (Safe). When any of
the quality criteria defined is not fulfilled, the Out of Lock is set (Fail).
The Out of Lock signal is isolated (2.000 Volts, 1 min).
1.2.3.c
SynCh1 - SynCh4: Analog Channels
The standard configuration for the digital outputs are four BNC connectors for coaxial cable
connections. All analog outputs are isolated (2.000 Volts, 1 min).
The GPS Sync includes an overload detection circuit. If there is a current demand higher than 1
A per channel (impedance lower than 20 ohms) the GPS Sync will reset itself.
Analog sync outputs are able to provide effective power of up to 0.25W per output. It can
provide 5Vpp to 50-Ohm loads connected at each of the four outputs. As an example, the GPS
Sync can synchronize twelve 600 ohm loads per individual output (48 loads in total). The
maximum number of devices that can be synchronized depends on the sensitivity level of the
devices (there are high sensitivity units that only require 1Vpp for synchronization).
Analog signal availability is dependent on the signal quality settings. These output signals are
generated when the DOP, C/N, number of satellites and elevation angles are within the
adjusted settings. It is possible to set the GPS Sync to generate these signals using the
integrated Real Time Clock (RTC) when GPS signal is not available or is below the required
quality levels.

1.2 Additional Functions
1.2.3.d
SynCh5 - SynCh8: Digital Channels
The standard configuration for the digital outputs are four pairs of multimode fiber optic with ST
connectors (62.5/125 nm).
As a factory option an 8-pin strip connector or BNC coaxial connectors can replace the fiber
optic ST connectors. All electrical output channels are isolated (2000V, 1min) to protect against
short circuits, overvoltage and surges. Digital outputs provide 5Volts TTL signals. Each digital
output has a driving capability of 250 mA.
In the models with High Accuracy 1PPS signal, SynCh5 provides a 0-5V TTL signal. If the port
has a BNC connector the positive signal is in the inner part of the connector.
Regular digital channels can also provide a timepulse signal.
Digital signal availability is dependent on the signal quality settings. These output signals are
generated when the DOP, C/N, number of satellites and elevation angles are within the
adjusted settings. It is possible to set the GPS Sync to generate these signals using the
integrated Real Time Clock (RTC) when GPS signal is not available or is below the required
quality levels.
1.2.3.e
SynCh9-Ch10: Serial Ports for ASCII Sync Messages
The default configuration of SynCh9-Ch10 is: 9600 bps, 8N1, and no flow control.
The serial port baud rate can be modified to 2400 bps, 4800 bps, 9600 bps, 19200 bps, 38400
bps, or 57600 bps.
ASCII synchronization messages will be provided through the DB-9 connector. TXD and GND
are the only RS232 available signals (DTE configuration). If required, the DTR signal provides
the TIMEPULSE signal or an output pulse
ASCII messages are generated by the integrated Real Time Clock (RTC). The ASCII message
generation is continuous and independent of the GPS signal reception.

1.5.3
Location Selection
Antenna mounting is crucial for optimal performance of the GPS.
When using patch antennas, the antenna plane should be parallel to the geographic horizon.
The antenna must have a full view of the sky to ensure a direct line of sight with as many visible
satellites as possible.
The distance between the antenna and the GPS Clock should be as short as possible. For long
distances, loss cabling such as LMR 400 or LMR200 should be used. For this type of cables,
lengths longer than 100 m are not recommended.
-
For LMR-200 cable, 40 meters (17 dB attenuation at 1.5 GHz).
For LMR-400 cable, 100 meters ( 17 dB attenuation at 1.5 GHz).
1.5.4
Required and Recommended Installation Elements
1.5.4.a

• Antenna Cabling
All common GPS antennas are designed for a 50 ohm cable connection between the antenna
and the receiver.
Low loss cabling such as LMR 400 or LMR 200 should be used. For this type of cable, lengths
longer than 100 m are not recommended. The connector on the GPS is SMA male type. The
connector on the antenna side depends on the selected antenna.
For distances between the antenna and GPS longer than 100 m1, a separate GPS Clock
should be installed closer to the antenna. The connection between the clock and synchronizer
uses a shielded 4 pair cable with circular connectors. Route this cable through metal conduit
wherever possible, in order to avoid external interference.
(*) 100 meters is the distance recommended for LMR400 low loss cable. Distance between the GPS and the GPS
antenna is highly dependent on cable selection.

Chapter 1. Description and Start-Up
1.5.4.d
Antennas
When selecting the antenna there are two main types to consider.
First, select either an active or passive antenna. Second, select a patch or helix antenna.
Passive Antennas contain only the radiating element, such as the ceramic patch or the helix
structure.
Active Antennas have an integrated low noise amplifier. This is beneficial for two reasons.
First, the losses of the cable no longer affect the overall noise of the receiver system. Second,
the receiver noise can be much higher without compromising performance. Active antennas are
more costly than passive antennas.
The type of antenna is of primary concern when installing the antenna. Some designs naturally
favour the patch type of antenna, as in rooftop applications. Others favour the pole like style of
the helix antenna.
Furthermore, it is important that the antenna’s main lobe points to the sky in order to view as
many satellites as possible with the maximum antenna gain. However, one must consider that
comparable antenna gain requires a comparable sized antenna.
Helix antennas with a reasonable size will therefore often show a lower sensitivity compared to
a reasonably sized patch antenna. A helix antenna might result in more satellites being detected
in difficult signal environments when directly compared with a patch antenna. This is because
the helix will more easily pick up reflected signals through its omni directional radiation pattern,
and therefore, the receivers can see more satellites.
1.5.4.e
Lightning Arrester
The GPS antennas located outdoors are exposed to lightning strike. Even though the GPS
Sync’s antenna circuit is protected, to ensure maximum protection, it is recommended to install
a lightning arrester. This element establishes a discharge connection to ground when lightning
strikes the antenna. The lightning arrester should be located as close to the antenna as
possible, connected to the antenna cable.

GPS Sync Physical Installation
1.5.5.a
Installing the GPS
GPS Sync can be installed into a 19” rack with a1U slot available or mural. All the pieces to
mount the unit in the rack are included in the GPS Sync box.
1.5.5.b
Grounding GPS
For safety reasons it is necessary to ground the GPS. Connect the ground screw to local
ground using a flat wide copper wire strap, and fasten it with the nut.
1.5.5.c
Installing the Antenna
Antenna installation depends on the antenna used. Follow the installation and grounding
guidelines of the antenna manufacturer.
1.5.5.d
Connecting the Antenna to the GPS Clock
Antennas often have an integrated cable. In this case, simply attach the cable connector to the
GPS Clock antenna connector. For distances longer than 100 meters it is recommended to
install a distributed GPS Clock, as stated under section 3.2 (if using LMR400 cable). To protect
the installation further, it is possible to connect a lightning arrester between the antenna and the
GPS Clock.
1.5.6
Safety Recommendations
Consider this safety advice for installing, managing and using the GPS:
1. Antennas, cables and lightning arrester are conductive elements. Do not touch them
during a storm.
2. Contact between the antenna components and the high voltage cables can cause
serious damages and even death.
3. Do not install the antenna where electrical arcs can be generated.
4. Keep away from the voltage lines while installing or uninstalling the antenna.
5. Keep the cable that connects the lightning arrester to the antenna at least to 1-meter
away from any high power cable.
6. Verify that both the antenna and the GPS are properly connected to the GPS.
7. Verify that all grounding systems are properly connected.
8. Equipment grounding should be installed by a licensed professional to comply with local
electric codes.
9. The cable that connects the lightning arrester to the antenna must always be connected
to ground, especially during handling and disconnection.
10. Place a visible danger sign in the antenna fixture.
11. Verify that the power is disconnected during GPS installation.

Functions and Description of Operation
3.1.1
Operation Modes
The GPS Sync has two operation modes:
-
-
Sync Mode (default). Functions:
o Receives sync / GPS status information from the GPS receiver unit;
o Creates sync messages;
o Transmits sync messages through the Sync Channels;
o Monitors internal status;
o Updates time information available on the display (optional).
Config Mode. Functions:
o Shows a configuration menu;
o Does not send sync messages through the Sync Channels;
o Receives sync / GPS status information from the GPS receiver unit;
o Updates time information available on the optional display.
3.1.1.a
Transition between Operation Modes
In GPS Sync models without the optional HMI (display & configuration wheel), the transition
between operation modes is determined by the DTR signal in the SRV port. The following
diagram shows the transition between operating modes.
SRV - DTR ON
Configuration Password
Config
SRV - DTR OFF
Sync
Figure 3.1.1: Transition Mode Example.
In GPS Sync models with HMI, the above transitions (SRV connection) also apply. The
configuration wheel is disabled when using the service port (SRV). The display will show,
“Configuring through the SRV port”.
Whenever the wheel is pressed twice within three seconds, the GPS Sync will require a
password. The correct configuration password will display a configuration menu. If the password
is entered incorrectly, the display will return to its original status. Exit the Config Mode by
selecting the Exit option.
If the GPS Sync is in Config Mode via the HMI, and an SRV connection is detected, it will be
ignored until the Exit option from the HMI is selected.

3.1 Operation Description
3.1.2
Start-up Sequence
GPS Sync Start-up Sequence will be:
-
3.1.3
Wait for GPS Clock start-up.
Wait for display initialization (if available).
Set up GPS Clock according to GPS Sync internal configuration. (If the HMI is available,
it will display all issued commands).
Wait for the GPS Clock to track all required satellites that fulfill the pre-defined quality
parameters (2 minutes maximum).
The display (if available) will show local time and information related to the quality of the
GPS signals acquired by the GPS Clock.
LEDs are updated.
Sync Mode operation is initiated.
Self Check Features
The GPS Sync has an internal watchdog supervising proper firmware runtime. In case of
unexpected behavior the GPS Sync will reset automatically.
Also, the GPS Sync has a received signal quality check. It the received signal does not match
the quality criteria established, the GPS Sync can be set to generate an internal clock signal.
The out of lock alarm will indicate the lack of suitable incoming signal.
The GPS Sync includes an overload detection circuit. If there is a current demand higher than 1
A in any of the analog channels (caused for example by a short circuit), the device will reset
itself.
3.1.4
Display
The HMI display provides different information depending on the operation mode:
-
Sync Mode: Local time and date, time zone, and signal source data are displayed.
Config Mode: When any key is pressed, and the SRV port is not connected, the Config
Mode is entered after password confirmation. The configuration menus are displayed.

Functions and Description of Operation
3.2.1
Introduction
GPS Sync supports several synchronization protocols, IRIG-B123/122 for analog sync outputs,
IRIG-B003/002 or customer defined TIMEPULSE for digital sync outputs (note: high accuracy
1PPS digital output if available is not programmable) and NMEA 0183 for the serial sync output.
Moreover, some parameters modify the behaviour of the above synchronization protocols. This
section describes how to configure the GPS Sync and lists the available configuration
parameters.
3.2.2
Configuration Options
There are two options to configure the GPS Sync:
1. Using a terminal emulator, such as Windows© HyperTerminal, through the GPS Sync
front serial port – SRV. The terminal emulator needs to be configured as follows:
-
Baud Rate: 9.600 bps
Number of data bits: 8
Parity: None
Number of stop bits: 1
2. Navigating the menus on the display through the configuration wheel (optional feature).
Navigate through the menus by rotating the configuration wheel. To select a menu option,
click on the configuration wheel.
Note: To enter the configuration mode, double-click the wheel (within three seconds) and enter the
correct password.
The same menu options will be available from either the front serial port or the configuration
wheel.
It is important to note that the GPS Sync will enter the configuration mode whenever the user
opens a HyperTerminal session (DTR active) or the user double clicks the configuration wheel
(if available). In either case the user needs to enter a valid password. The GPS Sync will not
deliver sync information through the SynCh channels until the configuration mode is exited. This
occurs either when the user finishes the terminal emulation session (SRV port – DTR inactive)
or the user selects the Exit option through the configuration wheel (note that if no activity is
detected from the configuration wheel during a period of 60 seconds, GPS Sync will
automatically exit the configuration mode).
3.2.3
GPS Configuration Parameters
Configuration parameters can be modified using a multi-level menu. In order to be able to
access this menu, a configuration password is required. The factory default password is “az”.

NTP
3.4.3.a
NTP Network Time Protocol Overview
NTP, which is documented in RFC 1305, is the most popular way of synchronizing network
devices.
1GPS gets its time from a stratum 0 time server (the GPS satellite system via its internal GPS
clock). To do so, 1GPS will create an NTP association with GPS. This association is created by
the 1GPS itself and does not need to be configured by the user. 1GPS acts as a stratum 1 time
server to stratum 2 NTP clients.
3.4.3.b
Configuration of NTP in the1GPS
To enable the NTP server of the 1GPS check the Enable checkbox in the NTP configuration
page. This way the 1GPS will create an NTP association with the GPS to synchronize itself and
act as an NTP server.
1GPS supports the use of MD5 authentication and up to 5 different Authentication Keys can
be configured. To add a key press the button Add and enter the desired values in the Key
number and Key fields. The MD5 key must be 8 octets long. 1GPS can operate 3 different
ways:
-
-
-
Unicast (point to point): an NTP client sends a request to the NTP server and this
answers with the time stamped response, and information about the quality of the time
(accuracy, jitter, stratum level,…). It is always enabled as long as the NTP server is
enabled.
Broadcast (point to multipoint): the NTP server sends periodic (every 64 seconds) time
updates to the broadcast address specified in the Broadcast IP field. To enable this
functionality be sure to check the Broadcast Enable checkbox. Authentication is not
enabled in this case.
Manycast (multipoint to point): manycast is a new feature of NTPv4 and serves for
automatic discovery and configuration. It works as follows: a multicast client trolls the
nearby network neighborhood to find cooperating manycast servers. Any NTP server with
manycast enabled will respond to the client’s request with his unicast address and then
establish an unicast communication. The client also has to authenticate the servers
(through MD5 in 1GPS), and evaluates the different time values (and their respective
quality attributes) received from them to decide which one is better. To enable manycast
in the 1GPS check the Manycast Enable checkbox. The Manycast IP field is the
broadcast/multicast IP address the 1GPS will be listening to.
Depending on the GPS coverage, it can take the 1GSP from 5 to 10 minutes to synchronize itself with the GPS
Clock.
Remember to SEND, APPLY and SAVE all the changes required so configuration is available in the 1GPS.

SNMP
3.4.4.a
Managing the 1GPS
1GPS hosts an SNMP agent that contains MIB variables whose values can be requested or
modified by an SNMP manager. 1GPS SNMP agent can also send unsolicited traps to certain
predefined hosts. Traps are unsolicited notifications that alert of certain network conditions.
1GPS SNMP agent supports SNMP version 1 (SNMPv1) and SNMP version 2C (SNMPv2C).
Both SNMPv1 and SNMPv2C use a community string as a security mechanism. All SNMP
managers that belong to a certain community string will be able to access 1GPS MIB variables.
3.4.4.b
Configuration of SNMP in the1GPS
The user may define up to 5 different communities. Each community may determine the type of
access to 1GPS MIB variables, i.e., read only (ro) or read and write (rw). The user needs to
enable both functionalities: SNMP and Traps.
SNMP agent is enabled by ticking the Enable checkbox. Once SNMP agent is up and running,
the user needs to activate traps notifications by ticking Traps Enable.
Next example shows how to define two communities. Community “public” will only have read
access to 1GPS MIB variables, community “private” will have read and write access to 1GPS
MIB variables.
-
Enter the Name (*) public for the community.
Define the type of Access: ro (read only) or rw (read and write). In this example will be
ro corresponding to read only.
Press Send button.
To add the second community, private:
Press the Add button
Enter the Name private for the community.
Define the type of Access, in this case rw corresponding to read and write.
Press Send button.
In addition to the SNMP, the following example shows how to define the host 192.168.1.135
where 1GPS will send SNMP traps. These traps will be sent according to SNMPv2C, being the
community string traprec:
-
-
Enter the name traprec for the Community (*).
Define the Type according to the format of the trap. The 1GPS supports three types of
traps: v1, v2c and inform type (with acknowledge by the host). In this case the type will be
v2c according to SNMPv2C.
Enter the IP address of the host where the 1GPS will send the traps. In this case:
192.168.1.135.
Enter the destination Port for the traps. By default is 162.
Press Send button.
(*) Alphanumeric string up to 12 characters.

Chapter 3. Functions and Description of Operation
Changes affecting SNMP configuration will not be applied at runtime so Apply button takes no effect in this
case. It is necessary to Save the changes and reboot the 1GPS so that the new configuration takes effect.
3.4.4.c
Traps
The 1GPS sends ColdStart traps (OID: 1.3.6.1.6.3.1.1.5.1), which are type 1 SNMP traps. A
coldStart trap signifies that the SNMP entity (the 1GPS), supporting a notification originator
application, is reinitializing itself and that its configuration may have been altered. These traps
have two information fields:
-
Uptime (OID in SNMPv2c: 1.3.6.1.6.3.1.1.5.1): the value is expressed in timeticks.
Enterprise (OID in SNMPv2c: 1.3.6.1.6.3.1.1.4.3.0): the value is expressed as an OID (in
this case OID value: 1.3.6.1.4.1.15732).

3.5.1
Introduction
This reference manual provides the information you need to configure the main SW features of
1GPS NTP synchronizer through the serial console port. This command line interface (CLI) is
also accessible via a telnet session.
3.5.2
Accessing the CLI
3.5.2.a
First Steps
Before you can access the CLI you need to connect a PC to the 1GPS console port. To do so,
run a terminal emulation program such as the Windows Hyperterminal, and open a serial
connection to the 1GPS serial port using the following configuration:
-
Speed: 115200 bps.
Data bits: 8.
Parity: None.
Stop Bits: 1.
Flow Control: None.
Note that you can also connect a dial-up modem to the 1GPS console port (null-modem cable)
in case you require an out-of-band management.
When you start a session on the 1GPS, a login and password are required. Same user name
and password are applicable as in the web interface, i.e., for user name admin, the default
password is passwd02; for user name guest, the default password is passwd01.
To have access to all commands and configuration parameters, you need to use admin
account.

SW Configuration GuideLines
3.5.3.a
Overview
The goal of this chapter is to show how to configure the main 1GPS features. It is also a quick
start guide that will help the user to become familiar with CLI commands.
A more detailed description of the CLI commands, configuration parameters and statistics are
presented in the CLI – Reference chapter.
3.5.3.b
Basic 1GPS Configuration
All 1GPS configuration parameters are organized in a directory structure. A directory groups all
parameters related to a certain functionality. A directory can be easily distinguished from a
configuration parameter as all directory names will end with a ‘/’ character.

3.5 CLI Command Line Interface
1GPS directory structure is listed below:
-
main/ It contains 1GPS general configuration parameters, such us host name,
administration accounts …
admin/ It contains 1GPS IP information, which will be used to administer 1GPS.
ntp/ 1GPS supports Network Time Protocol (NTP). Its configuration parameters can be
found under this directory.
snmp/ This directory lists both, the SNMP communities that can access 1GPS
configuration parameters and the destination hosts where 1GPS is to send SNMP traps.
• 1GPS User accounts
Two different user accounts are available for administering 1GPS:
-
admin: This user account has privileges to modify 1GPS configuration parameters. The
default login is admin and the default password for this account is passwd02.
guest: This user account can access the 1GPS configuration but no parameter can be
modified. The default login is guest and the default password for this account is
passwd01.
The user can change either the user name or the password for any of the above user accounts.
Next example shows how to change admin account user name to adm_usr and password to
ziv.
1GPSC /> get main ; This command shows general 1GPSC parameters

/main/adminlogin = adm_usr
1GPSC /> apply; This command applies 1GPSC configuration
1GPSC /> save (*); Don’t forget to save the conf to flash memory
(*) The user may apply a configuration to the 1GPS. This implies that all configuration parameters already
changed will be up and running in the 1GPS. Do not forget to issue save command if you want to save changed
configuration parameters to 1GPS flash memory.

• Name
The user can assign a name to the 3WT in order to identify it. By default, its value is 1GPS. The
user can modify the system name using the Set command. Next example illustrates how 1GPS
name is modified to 1GPS. Note that whenever you change the host name, the CLI prompt will
be updated with this value.
1GPSC /> set main/hostname 1GPSC; This command sets the new hostname
/main/hostname = 1GPSC; 1GPSC system prompt is updated with the new value
1GPSC /> get main/hostname
/
main/
hostname = 1GPSC; value for the hostname
• Site specific parameters
The user can configure specific site parameters such as 1GPS location (where the 1GPS is
located) and 1GPS contact (person to contact in case of events). These parameters will also be
used by the SNMP agent hosted by 1GPS.
Next example shows how to set 1GPS location to Building 1 – S.E. Madrid and contact to
grid@ziv.es.
1GPSC /main> set location "Building 1 - SE Madrid"
/main/location = Building 1 - SE Madrid
1GPSC /main> set contact grid@ziv.es
/main/contact = grid@ziv.es

Administration
To configure the IP address of the 1GPS the user can either enable the dhcp client of the 1GPS
or manually assign an IP address to the 1GPS. The main parameters involved are the IP
address and the subnet mask. The default gateway can be also configured so that 1GPS can
access remote networks.
Next example shows how to configure IP address 192.168.10.15/24 in the 1GPS. The default
gateway is 192.168.10.1.
1GPSC /> get admin; This command retrieves 1GPSC IP information
dhcpc = off
ip

1GPSC /admin> set ip 192.168.10.15; Set IP address to 192.168.10.15
admin/ip = 192.168.10.15
1GPSC /admin> set mask 255.255.255.0; Set mask to 255.255.255.0
admin/mask = 255.255.255.0
1GPSC /admin> set dgw 192.168.10.1; Set default gateway to 192.168.10.1
admin/dgw = 192.168.10.1
1GPSC /admin> apply; This command applies 1GPSC configuration
1GPSC /admin> save; Save to flash memory
The following example shows how to enable the dhcp client of the 1GPS:
1GPSC /admin> set dhcpc "on"
/admin/dhcpc = on; 1GPSC system prompt is updated with the new value
1GPSC /admin> get dhcpc
/
admin/
dhcpc = on; the DHCP client is ON
Once an IP address is properly configured, 1GPS CLI can also be accessed through a telnet
session.

SNMP – Managing 1GPS
1GPS hosts an SNMP agent that contains MIB variables whose values can be requested or
modified by an SNMP manager. 1GPS SNMP agent can also send unsolicited traps to certain
predefined hosts. Traps are unsolicited notifications that alert of certain network conditions.
The user needs to enable both functionalities. SNMP agent is to be enabled setting the
snmp/enable configuration parameter to on. Once SNMP agent is up and running, the user
needs to activate traps notifications by setting the snmp/trapenable configuration parameter
to on.
1GPS SNMP agent supports SNMP version 1 (SNMPv1) and SNMP version 2C (SNMPv2C).
Both SNMPv1 and SNMPv2C use a community string as a security mechanism. All SNMP
managers that belong to a certain community string will be able to access 1GPS MIB variables.
The user may define up to five different communities. Each community may determine the type
of access to 1GPS MIB variables, i.e., read only or read and write.
Next example shows how to define two communities. Community “public” will only have read
