Groupings 43
The Map shows a hierarchical view of the devices in your network
according to the selected grouping. By selecting a
Geographical grouping
for example, devices will be grouped according to which country they are
in. Within each country, devices may be grouped according to which city
they are in.
The hierarchy of groups in the Map corresponds to the order of attributes
in the selected grouping. Devices with the same value for the first
attribute, such as
Germany for example, are grouped together. Within
each country group, devices with the same value for the second attribute,
such as
Munich , are grouped together. You can further refine the
hierarchy by adding attributes to the grouping: a third attribute
Department1 , for example.
If a device does not have a value assigned to it for an attribute, then this
device may appear in a group called
unassigned . The unassigned group is
known as a redundant group. You can collapse redundant groups, so that
devices within them appear in a higher-level (assigned) group instead.
Predefined Groupings There are four predefined groupings in Traffix Manager:
■
DNS — Devices are grouped according to their DNS name.
This grouping is made up of the predefined attributes Network Layer
Type (for example, IP, IPX, DECNet, ATALK), and DNS Layer 1 through
DNS Layer 8. See
Table 5 for more information about these attributes.
■
Type and Network — Devices are grouped by their Network Layer
Type and network address.
This grouping is made up of the predefined attributes NL Type and
Network . All devices in the Map have both of these attributes
assigned so there are no redundant groups. See Table 5 for more
information about these attributes.
Within this grouping, devices are grouped by their major protocol
classes, that is, their NL Type, and are then further grouped in a way
appropriate to each protocol. For example, DECNet devices are
grouped by DECNet Area, IPX devices are grouped by IPX domain and
IP devices are grouped by class A/B/C Subnet.
If you use subnets other than class A/B/C at your site, you may want to
create a site-specific subnets grouping. You can create a customized
view of IP subnets in your organization in the following way:
