About WMS Groups
Grouping allows portions of an enterprise segment to be viewed according to criteria appropriate for
different management tasks. Further, grouping devices helps simplify complex management tasks by
allowing otherwise repetitive tasks to be applied to device groups as opposed to one device at a time.
Groups are always virtual in nature. Groups maintain only device references and not real device
instances. The life cycle of a device is not determined by the groups they belong to. If an administrator
deletes a group, all device references within that group are deleted, but the actual device remains
present in WMS. If a device is a member of a different group, it will continue to be a member of that
group despite its deletion from the other group.
Groups are classified into System, Static, and Dynamic categories. These classifications have the following
membership conditions:
NOTE
Devices in the My Groups tab can appear in more than one group.
● System - By default, WMS supports a set of pre-defined groups created in respect to the commonality
of the devices supported within the group. You cannot add an additional group as a system group.
Pre-defined system groups include:
● All Wireless Controllers- Contains the wireless controllers (across all sites) discovered by WMS
● All Access Points - Contains the access points (across all sites) discovered by WMS
● Static - A static group is one whose membership is fixed at the time the group is created and does
not automatically change based on network conditions. The membership of a static group changes
only if the user manually edits it or if a member device is purged from the WMS database. If the
group is static, the WMS administrator has to provide the list of included devices when creating the
group.
● Dynamic - A dynamic group is one whose membership is based on membership criteria defined
when the group is created. The membership of the group is periodically re-evaluated (automatically)
based on changing conditions. The list of group members may increase or decrease as the number of
devices that meet the defined membership criteria changes. Users cannot add or delete devices, as
dynamic groups are defined using the filter criteria set.
Groups can be created based on one or a combination of grouping criteria, including: IP Address, MAC
Address, Model, Device Type, Firmware Version, Site Name and System Name. However, not all grouping
criteria apply to all types of elements and devices.
NOTE
When a device is permanently deleted from the network, WMS removes its reference from relevant groups. If a
device is detected as missing, it is automatically removed from any dynamic group to which it belonged. If the
device is later determined to no longer be missing, it can be added to any dynamic group for which it meets the
membership criteria.
