Network Device Groups

Network Device Groups

In ACS, you can define network device groups (NDGs), which are sets of devices. These NDGs provide logical grouping of devices, for example, Device Location or Type, which you can use in policy conditions.

When the ACS receives a request for a device, the network device groups associated with that device are retrieved and compared against those in the policy table. With this method, you can group multiple devices and assign them the same policies. For example, you can group all devices in a specific location together and assign to them the same policy.

You can define up to 12 network device groups.

The Device Group Hierarchy is the hierarchical structure that contains the network device groups. Two of these, Location and Device Type, are predefined; you cannot change their names or delete them. You can add up to 10 additional hierarchies.

An NDG relates to any node in the hierarchy and is the entity to which devices are associated. These nodes can be any node within the hierarchy, not just leaf nodes.

Note You can have a maximum of six nodes in the NDG hierarchy, including the root node.

Step 2 Do any of the following:

•Click Create.

•Check the check box next to the network device group that you want to duplicate, then click Duplicate.

•Click the network device group name that you want to modify, or check the check box next to the name and click Edit.

The Hierarchy - General page appears.

Step 3 Modify the fields in the Hierarchy - General page as described in Table 7-1:
