44 CHAPTER 4: GROUPING NETWORK DEVICES IN THE MAP
a Add appropriate entries to the SubnetsDB configuration file. See
Appendix D
, “Using the SubnetsDB File”, for details.
b Either start a new database or use Reload Attributes... with Subnets
checked to update the attributes of existing devices in the database.
c Create a new grouping using the following attributes (in the order
given):
■ NL Type.
■ Subnet.
■ Deselect Collapse Redundant Grouping.
d Select this grouping.
The IP group will then contain all the devices matching an entry in
your SubnetsDB files, grouped by subnet name. The unassigned group
will contain the rest of the IP devices, grouped by class A/B/C subnet.
■ MAC and Type — This grouping is useful for looking at all the
different types of network traffic (for example, IP, IPX, DECNet) being
generated by a given physical device.
This grouping is made up of the MAC Address attribute and the NL
Type attribute. See Table 5
for more information about these
attributes.
■ Vendor and MAC — This grouping is useful for identifying devices
from different vendors. It is made up of the Vendor attribute and the
MAC Address attribute. See Table 5
for more information about these
attributes.
Creating and
Assigning Attributes
You must create attributes, or select predefined attributes, to include in
each grouping you want to create.
There are two methods for creating and assigning attributes:
■ Set up automatic creation and assignment of attributes using
user-defined automatic attribute assignment and your own data
sources. See Appendix E
, “Automatic Attribute Assignment” for more
information.
■ Create attributes and assign values to devices in the Map using the
Attributes dialog box. You can create any number of attributes in
advance, and then assign values for these attributes to selected
devices at any time.
