3. In the Name field, provide a name for the network to be scanned (for example, Accounting Network ).
4. In the Network field, define the IP network range, or the first IP address on the network, to be scanned. One
example would be 10.52.0.0.
5. Enter the Subnet Mask for the network to be scanned (for example, 255.255.252.0). The largest subnet
AWMS supports is 255.255.0.0.
6. Click Add .
7. Repeat these steps to add as many networks for which to enable device scanning. All network segments
configured in this way appear in the Network section of the Device Setup > Discover page.
8. Complete the configuration of scan credentials, then combine scan networks and scan credentials to create
scan sets. The next two procedures in this section describe these tasks.
Adding Credentials for SNMP/HTTP Scanning
The next step in SNMP/HTTP device discovery is to define the scan credentials that govern scanning of a given
network. New APs inherit scan credentials from the System Credentials that you configure on the
Device Setup
> Communications page.
Perform these steps to define scan credentials for SNMP/HTTP scanning:
1. Locate the Credentials section on the Device Setup > Discover page. This page displays scan sets, networks,
and credentials that have been configured so far, and allows you to define new elements for device scanning.
2. To create a new scan credential, click Add New Scan Credential . Figure 77 illustrates this page.

3. Enter a name for the credential in the Name field (for example, Default ). This field supports alphanumeric
characters, both upper and lower case, blank spaces, hyphens, and underscore characters.
4. Choose the type of scan to be completed ( SNMPv1, SNMPv2, or HTTP ). In most cases, we advise that you
perform scans using SNMP for device discovery, but the following are considerations you should factor in to
your decision:

SNMPv1 and SNMP v2 differ between in their supported traps, supported MIBs, and network query
elements used in device scanning.

HTTP discovers devices using the HyperText Transfer Protocol in communications between servers and
additional network components. HTTP is not as robust in processing network events as is SNMP, but
HTTP may be sufficient, simpler, or preferable in certain scenarios.
