The Configuration Management Process
The Configuration Management Process
Configuration Management involves identifying, controlling, and monitoring
the “managed objects” that make up a communication network. A managed
object is any device that is modeled in the SPECTRUM database. These
include not only hardware devices such as PCs, workstations, hubs, and
routers, but also software applications on these devices. ECM uses the
management modules developed by Cabletron to manage the configuration of
these objects.
SPECTRUM continually monitors the network, maintaining a database of
information about every managed object on the network. Enterprise
Configuration Manager obtains the values of the attributes in the
configuration by interrogating the SPECTRUM model of the managed object.
The ECM administrator uses this information to manage the network. With
ECM, the administrator can capture existing configurations or create new
ones, load configurations to devices anywhere on the network, and then verify
whether configurations have changed.
About ECM Templates
Enterprise Configuration Manager allows you to create configurations with
templates or manually without templates. Before you begin working with
ECM, it is important for you to understand the difference between ECM
templates and configurations.
A template is a list of attributes for a specific device and its subdevices, if
selected. You use ECM templates for only one operation — capturing the
configuration of a device. When you create a template, Enterprise
Configuration Manager provides a list of all readable/writable and non shared
attributes for that type of device (with subdevices, if selected). In ECM you
select the attributes you want to include in the template. Depending on the
purpose of the template, your template might contain a single attribute (port
status, for example) or dozens of attributes.
When you use templates to capture the configuration of an existing device,
Enterprise Configuration Manager captures the instance IDs, if any, and the
values of the attributes listed in the template. The attributes listed in the
template plus the instance IDs and attribute values captured by ECM make
up the new configuration.
Remember: A template is only a list of device-specific attributes, whereas a
configuration is a list of device-specific attributes with instance IDs, if
applicable, and their values. See Figure 1-1.
