Adding Credentials For Scanning - Dell PowerConnect W-AirWave 7.6 User Manual

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