6. Click Add.
Figure 53 shows an example of adding a scan network called Accounting Network, where the network IP address
is 10.52.0.0, and the subnet mask is 255.255.255.0.

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 devices 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. Figure 54 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:
l SNMPv1 and SNMP v2 differ between in their supported traps, supported MIBs, and network query
elements used in device scanning.
l 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.
