Once the configuration is pushed, the unchecked fields from the Global Group appears on the Subscriber Group
as static values and settings. Only fields that had the override checkbox selected in the Global Group appear as
fields that can be set at the level of the Subscriber Group. Any changes to a static field must be made on the
Global Group.
If a Global Group has Subscriber Groups, it cannot be changed to a non-Global Group. A Global Group without
Subscriber Groups can be changed to a regular Group by updating the setting on the Groups > Basic
configuration interface.
Device Discovery Overview
After you have deployed W-AirWave on the network, the next step is to discover all existing devices connected to
your network. W-AirWave allows device discovery through SNMP/HTTP scanning and CDP polling of Cisco
switches and routers.
SNMP/HTTP Scanning Overview
In order for W-AirWave to discover devices on your network, you must first enable SNMP/HTTP scanning from
the Device Setup > Discover page and then configure SNMP/HTTP scanning.
This page is only visible to users with the W-AirWave Administrator role or roles that have Allow authorization of
APs/Devices enabled in AMP Setup > Roles.
This process includes:

l "Adding Credentials for Scanning" on page 120
l "Defining a Scan Set" on page 121
l "Running a Scan Set" on page 121
Adding Networks for SNMP/HTTP Scanning
The first step when enabling SNMP/HTTP scanning for devices is to define the network segments to be scanned.
To add networks for SNMP/HTTP scanning:
1. Go to the Device Setup > Discover page.
2. Scroll down to the Networks section, and click Add.
3. Enter a network name.
4. Enter the IP network range to be scanned. Or, enter the first IP address on the network.
5. Enter the network subnet mask. The largest subnet W-AirWave supports is 255.255.255.0.
