SNMP Types

When performing an SNMP inventory scan, Docusnap looks for the available SNMP devices. However, no information is returned on the type of the identified device, for example, whether it is a switch, a router or a printer. In the SNMP Types tab, you can define keywords that will be compared with the identified SNMP equipment. Then, Docusnap is able to indicate the correct type in the tree view and reports. The value that will be used for comparison with the keyword is specified in the Description column of scanned devices.

The SNMP Types tab lists predefined keywords that are often used for SNMP devices. Click the New button to add a new keyword for SNMP types. Enclose the keyword in percentage symbols (%). These symbols are placeholders; they replace the remaining words in the description. The keyword you enter must exist in the description of the SNMP device. Otherwise, the correct type will not be found.

Keywords are evaluated at two different points in time:

• During the inventory scan: The keyword is compared with the Description of the SNMP device and, in addition, with its host name. The resulting type is stored with the device.
• When displaying the device in the tree view and in reports: The type is determined again, but this time based on the Description of the latest scan only.

As a result, new or modified keywords take effect immediately for devices that have already been scanned - provided that the keyword is contained in the Description. A new scan is not required in this case. If no keyword matches the description, the type determined during the inventory scan is used. This is how an assignment that was based on the host name only is retained. Consequently, a keyword that matches the host name only will not take effect until the next inventory scan.

A manually assigned SNMP type always takes precedence and is never overwritten by the keywords.
