4.1.2 Credentials used in discovery from IP address
When searching with IP addresses, devices are discovered with the use of ARP and ICMP, but detailed information about the devices is not collected. To collect the detailed device information during the search, you need to specify credentials for the discovered devices so that the devices can be connected by using SNMP or a Windows administrative share.
- SNMP credentials
-
Community name
- Credentials for Windows administrative share
-
-
User ID with administrator permissions
-
Password
-
For a device for which SNMP can be used, if community authentication is possible, the device type as well as part of the device information can be collected when it is discovered.
For a computer for which Windows administrative shares are enabled, if logon authentication with administrator permissions is possible, the device type as well as most of the device information can be collected when it is discovered. In addition, the agent can be delivered and installed.
- Important note
-
The device type of a computer with the following OSs: Windows Me, Windows 98, Windows 95, and Windows NT 4.0, might be classified as Unknown after discovery.
- Important note
-
If multiple network cards are used for a single device, when a search is performed using ICMP, the device is discovered as multiple devices.
- Tip
-
Specify a user ID to be used in authentication for Windows administrative shares in the following format if the ID is to be authenticated as a domain user: User ID@FQDN (fully qualified domain name), or domain name\user ID. The fully qualified domain name is a format in which no host name or domain name are omitted. For example, specify an ID in the following format: User001@PC001.hitachi.com.
- Tip
-
If Windows administrative share authentication is used, administrative share setting of a computer must be enabled in advance.
A search is performed by combining credentials for each discovery range. By default, all the specified credentials are used for discovery. If, however, SNMP community names differ among departments, or the Windows credentials differ among computers, you can perform a search by selecting the credentials necessary for each discovery range.
Note that the credentials used in discovery from IP addresses are also used when the agent is delivered. To deliver the agent after discovery, in the Settings module, select Discovery and then Configurations, and in the IP Address Range view, specify Windows administrative share credentials for the discovery range that includes the computer to which the agent is to be delivered.
