5.15 SNMP
The Simple Network Management Protocol (SNMP) is part of the internet protocol family. It was
developed to control and monitor network elements (Router, Server, Switches, etc) from a central
management station.
SNMP defines a community based administration framework, using it to administer the different SNMP
elements. Each SNMP community is a group of units, which includes at least an agent and a
management system. The characteristics of managed network components which can be accessed and
modified via an agent, the so-called
„managed-objects”, will be defined in the Management Information
Base (MIB).
5.15.1 Access Control
The SNMP protocol does not include access or password control mechanisms. In the SNMP access
control you can regulate the access and authorisation which are available via SNMP.
Command
Description
Community Name
Name of the SNMP community to which the router should belong.
Each SNMP community should have at least one SNMP agent
and belong to a managed system. It does make sense, that a
community consolidates different working groups (e.g. Internet,
printer, sales, marketing, etc). Individual SNMP agents can also
be represented in different communities (e.g. routers)
Source:
Default:
All SNMP requests will be answered
Hostname:
SNMP requests from the defined host will be
accepted
Subnet:
SNMP requests from the following networks (IP
address/Subnet e.g. 10.1.4.0/24) will be accepted.
Restricted OID:
None:
Access to the total MIB permitted
OID:
The value OID controls the accesslevel of the MIB
(Management Information Base) tree; it will only grant access
underneath the entered value. The MIB contains the definition of
all properties, which can be selected or modified via SNMP.
Access Mode:
Read Only:
Within the MIB, only read access is permitted. When
using this, the SNMP can therefore only interrogate the respective
status and properties, but not make any changes.
Read/Write:
Within the MIB, read and write access is permitted.
When using this, the SNMP can therefore interrogate the
respective status and properties and make changes
Process:
Activates/deactivates this community
5.15.2 Sysinfo Setup
The RFC1214-MIB definition includes various manageable objects and function groups. To clearly
organise these objects and function groups, you can use the SNMP Sysinfo Setup to define the value
sysLocation and SysContact for the router.
Command
Description
System Location
Informative information about the physical location
