Preparing Devices
for Management
The ability to set up devices from the SNMP management station is an
important part of your configuration management strategy. To prepare to
manage devices on your network, you need to perform the following key
tasks:
1
Discover devices and create network maps — The management system
organizes your network into a hierarchical series of maps and submaps.
This structured, hierarchical approach provides a high-level submap that
represents your entire network, and detailed views of portions of the
network, which helps you analyze and troubleshoot your network. Each
map contains objects and symbols that represent parts of your network.
Map symbols represent network resources as graphical icons, and relate
to a set of basic management information that is stored in the
management system’s object database.
2
Set up SNMP parameters — The management station uses SNMP to
get
and
set
management information on the agent. To make sure you can
manage devices on your network, you need to set the SNMP parameters
that affect how the system communicates with devices.
Whenever a management application requests information from an
SNMP agent, it provides a
community name
. The community name is a
text string that acts as a password, and is used to authenticate every
packet that is sent from the management application and the agent.
The management station must use the same community name that is
configured on the agent. Setting the community name determines your
level of management control over the device.
Some advanced management platforms enable you to set global values
for other SNMP parameters, such as time-out and retry values, polling
intervals, and SNMP proxy agents, that affect the way you manage
devices.
For the CoreBuilder 9000 Enterprise Switch, you must configure the EME
with certain parameters before you access the Administration Console of
any switch fabric module or interface module, and before you access the
system through an external Simple Network Management Protocol
(SNMP) application. See the
CoreBuilder 9000 Enterprise Management
Engine User Guide
for more information.
3
Start polling device status — Map symbols can show the status of the
managed object, so you can use your network map to quickly find out
the state of the resources that make up your network.
