Receiver Setup: Snmp - Leica GR10 Operational Manual

Receiver setup: SNMP

Background Information
Simple Network Management Protocol (SNMP) is an Internet-standard protocol for managing devices on IP networks, in this
case the GR/GM series receiver. It can be used in network management systems to monitor the GR/GM receiver for conditions
that warrant administrative attention. It can also be used to monitor other IP based network devices like routers, switches or
modems, as many modern network devices support the SNMP protocol. This means that by using SNMP protocol all the
devices of the network infrastructure (communication devices and GNSS receivers) can be monitored if they support SNMP.
This may help in tracking down network issues, like malfunctioning routers, bandwidth issues and other problems that may
affect the availability and reliability of GNSS network services.
Talking in SNMP terminology, there is always an agent (e.g. the GR/GM series receiver) and a manager (e.g. a network
management/monitoring system). An agent provides information that has to be requested by the manager.
Setting Descriptions
The table below describes the settings that can be configured on the SNMP page in order to activate the SNMP agent on a
GR/GM receiver.

It is highly recommended that SNMP is not enabled when the receiver is connected to the Internet. The
SNMP community string authentication is sent unencrypted and considered a high security risk.
GR/GM series receivers supports SNMP versions v1, v2p and v2c.
Many different status variables can be queried and monitored using SNMP, for example:
Description
Activate to allow SNMP access on port 161 via UDP. It allows a manager to query
MIB (Management Information Base) objects from the receiver.
Enter the community name. This is essentially a password to authorize access to the
GR/GM receiver when using SNMP. The community string is received with every
request and the GR/GM receiver will only reply if the same string was sent as
configured in this text field.
The GR/GM series receivers only support 'read-only' access, independent of the
community string configured. 'Read-write' and 'trap' access is not supported at this
stage.
Per default the Community name is set to public.
Community strings are case sensitive.
Enter the location of the receiver (e.g. the address) to easily find it in case
maintenance is needed. This field can be left blank.
Enter the name and/or email address of the person responsible for this receiver to
easily get in contact with, in case maintenance is needed. This field can be left blank.
Press to store the SNMP settings.
