Using SNMPUtilG

You can run SNMPUtilG from the Start menu (where it is called SNMP Query Utility), or from the command prompt or Run line (by typing snmputilg).

The tool starts with the loopback address 127.0.0.1, the object identifier .1.3.6.1.2.1, and the "public" community selected. These values can be changed to select another system by IP address, select another object identifier farther down the tree, or select another community as necessary.

If another system IP address is selected, then that system must be running the SNMP service. The target system must also be configured to allow access from the network address from which the tool is run. By default, Windows 2000 allows access from all other IP addresses.

If another community is selected, then the community must exist, and READ privileges must be granted to that community. You can verify and add communities using the SNMP Service. The ability to configure community permissions exists only in systems running Windows XP Professional, Windows 2000 or Windows NT version 4.0 Service Pack 4. The ability to restrict access by IP address exists in all versions of Windows XP, Windows 2000, and Windows NT.

The SNMP Function to Execute drop-down box is used to select the desired operation, followed by selecting the Execute Command button. Functions include:

• GET the value of the current object identifier
  
  
• GET the NEXT value after the current object identifier (this is the default)
  
  
• GET the NEXT 20 values after the current object identifier
  
  
• GET all values from object identifier down (WALK the tree)
  
  
• WALK the tree from WINS values down
  
  
• WALK the tree from DHCP values down
  
  
• WALK the tree from LANMAN values down
  
  
• WALK the tree from MIB-II down (Internet MIB)

The results are listed on the screen.

The results can be cleared, saved, or updated from the Context menu, which is selected by right-clicking. From the Context menu you can:

• Copy one or more records to the clipboard
  
  
• Clear contents of the list view now
  
  
• Clear list view after executing each command
  
  
• Requery the currently selected record
  
  
• Dump all records to a comma-delimited text file
  
  
• Edit (SET) the value of this object identifier

Caution

• Even though many object identifier values are read-only by default, you should use caution when using the SNMP SET command. Incorrect use of this tool might cause network name resolution or network connectivity problems that can adversely impact performance.
