Dell PowerConnect W-AirWave 7.5 | User Guide Discovering, Adding, and Managing Devices | 109

1. Locate the Credentials section on the Device Setup > Discover page. (Scroll down if necessary.) 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, select the Add button to add a new scan credential. Figure 73 illustrates this

page. (Note that you may have to scroll down the page again to view this section.)

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, perform scans using

SNMP for device discovery, but consider the following factors in 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.

a. If you selected SNMPv1 or SNMPv2, then define and confirm the Community String to be used during

scanning. In this section, the community string used can be either read-only or read/write, as AirWave

only uses it for discovering APs. To bring APs under management, AirWave uses the credentials supplied

in the Device Setup > Communication SNMP section. Once the device is authorized, it will use the non-

scanning credentials.

b. If you selected HTTP for the type, then enter a Username and Password for the scan credentials.

5. Select Add after you have completed the previous steps. The Device Setup > Discover page displays the new

scan credential or credentials just created or edited.

6. Repeat these steps to add as many credentials as you require.

7. Once scan networks and scan credentials are defined, combine them by creating scan sets using the next

procedure: “Defining a Scan Set” on page109.

Defining a Scan Set

Once you have defined at least one network and one scan credential, you can create a scan set that combines the

two for device discovery. Perform these steps to create a scan set.

1. Locate the Scan Set area at the top of the Device Setup > Discover page.

2. Select Add New Scan Set to see all scan components configured so far. If you wish to create a new network, or

new scanning credentials, you can select Add in either of these fields to create new components prior to

creating a scan set.

3. Select the Network(s) to be scanned and the Credential(s) to be used. AirWave defines a unique scan for

each Network-Credential combination.

NOTE: AirWave automatically appends the type of scan (SNMP or HTTP) to the Label.
