COMMUNITY NAMES

When using Local or Remote management tools to access the EMME, it
is important that the network manager has the ability to maintain network
security. Community names provide some network security by serving as
passwords to the device and the software running it. The network
manager (super user) establishes three (3) passwords, each of which
controls varying levels of access to the hardware and software. The
Community names are set through the Local Management SNMP
Community Names Table. Once these are set by the network manager,
they can be maintained in confidence or limited to users who have a need
to manage the system.
The three levels of access are:
• Super-User - Allows full management privileges
• Read Write - Allows edit of device configuration parameters not
including changing Community names
• Read Only - Allows reading of device parameters not including
Community names
1.8 SNMP (SIMPLE NETWORK MANAGEMENT
PROTOCOL)
SNMP is a protocol within the TCP/IP protocol suite. Network
applications such as Local Management and MIB Navigator use SNMP to
manage device configurations and monitor operating conditions. SNMP
protocol defines methods for "GETs," "SETs," and "TRAPs," either
remotely from any point along the TCP/IP network or locally. This allows
for control of the device from any point along the network. MIB
Navigator uses the Management Information Base (MIB), located on the
device to be managed, to access information (GET), change device
parameters (SET), and to notify preselected users that an event has
occurred (TRAP).
