SNMP Tools (Core and Advanced) Description

Purpose of the SNMP Tools

• The purpose of this tool is to create SNMP queries to send to a target then display the response from the target. If the target is running SNMP and you have the proper access credentials, you can gain an enormous amount of information about the target.

This tool is currently IPv4 only. IPv6 migration will be occurring at some point during the v11 series.

SNMP Tool Capabilities

• [Select OID...] button (core). This is used to bring up a selection tree for choosing the OID (object identifier) number to use during your queries. OIDs are like database indexes to a particular object of data which may be static or dynamically updated in real time. This selection tree is built using the currently loaded OIDs.
• Walk (core). OID numbers are organized in a directory tree structure, the walk command will allow you to view all the subitem entries and their data values for a particular parent OID.
• WalkBulk (core, v2c/v3 only). This differs from the Walk function above in that a group of subitem data values can be retrieved with each request. The final result is the same, it is more efficient. You can define how many items you will accept using 'max bulk reps'.
• Get (core). This feature "gets" the single data value or string associated with a specific OID.
• GetNext (core). This feature "gets" the next data value or string after a specific OID.
• GetBulk (core, v2c/v3 only). This feature "gets" the data value or string associated with a specific set of OIDs beginning with the one you entered. Similar to WalkBulk except that only the item count you enter in 'max bulk reps' is used.
• Set (core). This feature "sets" the data associated with a specific OID to a new value. The Set dialog appears with a means to select the type of data entered and the value.
• OID Conversion (core). There are two of these features. One is for converting from a numeric OID to a more human friendly text representation and the other reverses the procedure. This depends on the text of the MIB to be present. You can easily add your own MIBs into this program.
• Get Status (core). This query requests for a number of OID entries to provide you with a quick look into the status of the target system such as interface count and status.
• Routing Table Report (advanced). Shows the IPv4 routing table from the target.
• Arp Cache Report (advanced). View the current arp cache on the target.
• Listening Ports Report (advanced). Show the listening ports on the target.
• System Info Report (advanced). Shows system description, time since boot, system name, location, contact and more.
• SNMP Dictionary Attack Tool (advanced) - uses password guessing to recovery the community name (password) from an SNMP v1/v2c device. Can scan a set of devices simultaneously. More information.
• SNMP Scanner Tool (advanced) - similar to the Dictionary Attack tool except instead of guessing the community name, you give it a list of expected community names. You also give it a list of IPs.
