3. In the Na

me field, provide a name for the network to be scanned (for example, Accounting Network).

4. In the Ne

twork 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 Sub

net 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 en

able 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. Th

e 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 credential

s for SNMP/HTTP scanning:

1. Locate the Cre

dentials 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.

vice Setup > Discover > Add/Edit New Scan Credential Section Illustration

3. Enter a name for the credential in the Na

me 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, S

NMPv2, 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.
