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.
5. 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 AWMS only uses it for discovering APs. To bring APs under
management, AWMS uses the credentials supplied in the Device Setup > Communication SNMP section.
NOTE: AWMS automatically appends the type of scan (SNMP or HTTP) to the Label.
Once the device is authorized, it will use the non-scanning credentials.
6. Select Add. The Device Setup > Discover page displays the new scan credential or credentials just created or
edited.
7. Repeat these steps to add as many credentials as you require.
8. Once scan networks and scan credentials are defined, combine them by creating scan sets using the next
procedure:

Defining a SNMP/HTTP 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. AWMS defines a unique scan for each
Network-Credential combination.
4. Select Add to create the selected scans, which then appear in a list at the top of the Device Setup > Discover
page.
5. To edit an existing scan, select the pencil icon next to the scan on the Device Setup > Discover page.
6. When ready, proceed to the next task,
NOTE: Scheduling an HTTP scan to run daily on your network can help you to discover rogues. Some consumer APs, like most D-
Link, Linksys, and NetGear models, do not support SNMP and are found only on the wired side with an HTTP scan. These devices
are discovered only if they have a valid IP address. Proper credentials are not required to discover these APs. Wireless scans and
the AMC discover these rogues without any special changes.
