Key Concepts 39
A VLAN sub-group is considered unique if it has a unique VLAN ID and
a unique name. The name is case sensitive, so a VLAN named
'marketing', with a lowercase 'm', is considered different to a VLAN
named 'Marketing', with an uppercase 'M'. VLANs with the same ID
and name on either side of a router are considered to be the same
VLAN for the purposes of the VLANs group.
Devices with no available VLAN information are added to a specific
'Undetermined' VLAN sub-group as shown in Figure 12
.
Figure 12 VLAN Groups
All sub-groups listed under the 'VLANs' group are sorted first by VLAN
ID, then by VLAN name. If the 'Undetermined' sub-group is present, it
is added as the first group in the VLANs group.
