Use the MIB Browser

When investigating and diagnosing network problems, it may be useful to query a node for SNMP MIB Variable values. This technique can provide real-time information about the node that is in addition to that information stored in the NNMi database. This topic includes the following sections:

MIB Browser Prerequisites
Run SNMP Walk Commands (MIB Browser)
Run SNMP Set Commands (MIB Browser)
Use Aliases in MIB Browser Commands
View MIB Browser Results
Save MIB Browser Results to a CSV File
Print MIB Browser Results

Access to these commands depends on the NNMi RoleDetermined by your membership in one of four special NNMi User Groups (NNMi Administrators, NNMi Level 2 Operators, NNMi Level 1 Operators, or NNMi Guest Users). This membership determines what you can see and do within the NNMi console. and Object Access Privileges to which you are assigned. If you are unable to access an action, contact your NNMi administrator.

If your NNMi Security Settings allow, you can use NNMi's MIB Browser to perform the following tasks:

SNMP Walk
This command gathers real-time responses to one or more questions (MIB Variables). The range and complexity of the queries is limited only by the target Node's associated SNMP Agent configuration for MIB fileManagement Information Base files are the basic building block of SNMP communication protocol. SNMP Agents are configured to respond to requests defined by a group of supported MIB files. support.
In the MIB Browser, specify Node and the query starting point (OID of the MIB), then click the Walk button to generate responses from the SNMP Agent for MIB Variables from any designated starting point down though the MIB structure.
To display the responses obtained from another location in the Internet MIB structure, change the OID attribute value (MIB object identifier).
SNMP Set
This command makes a real-time change on the target Node. For example, you could issue an SNMP Set for the SNMPv2-MIB's MIB Variable named sysContact to let everyone on your team know that you are assigning someone new to that Node.

See the following topics for details:

MIB Browser Prerequisites

Confirm the following items to ensure best results from your MIB Browser queries:

Verify that the Node you want the MIB Browser to query responds to SNMP Get and Set commands. See SNMP Agent State settings on the Node Form.
Verify that the MIB files defining the MIB Variables you want to use are supported by the target Node's SNMP Agent. See Determine which MIBs a Specific Node Supports.
Verify that the MIB files defining the MIB Variables you want to use are installed on the NNMi management server. See MIB Variables View.
Contact your NNMi administrator with requests for loading additional MIB files on Nodes or the NNMi management server.

MIB Browser Menu Items
Menu Item
Tools	→ Diplay MIB File	Displays the MIB File (text source file) where the selected OID is defined. See Display a MIB File (source text file).
	→ List Supported MIBs	Determine which MIBs are installed on the selected Node. The resulting list determines which SNMP Walk and Set choices you have for this Node. Click the links on the displayed list to open a MIB Form. It is easier to review each available MIB Variable within this context than within the source text file.

Run SNMP Walk Commands (MIB Browser)

You can use the NNMi MIB Browser to gather a wealth of real-time information from devices in your network environment. The list of available questions are defined in MIB files as MIB Variables, each with a unique OID. See Explore SNMP MIB Source Information.

To gather information from a particular Node in your network environment:

Verify the MIB Browser Prerequisites.
Access the MIB Browser.
Level-2 Operators and above, do one of the following:
- Select Tools → MIB Browser.
- In any map or Node table view, do one of the following:
  - Click a Node and select Actions → MIB Information → MIB Browser.
  - Right-click a Node and select MIB Information → MIB Browser
- In any Incident view, double-click an Incident to open the Incident form:
  1. In the Source Node attribute, click the drop-down, and select Open.
  2. In the Node form, select Actions → MIB Information → MIB Browser.
- Within the MIB Form or MIB Variable Form:
  Select Actions → MIB Information → MIB Browser.
Node: The Node Name or IP address of the Node whose MIB Variable values you want to collect.
Read Community String: (Optional) Do one of the following:
- Leave this attribute value blank. NNMi uses the read community string currently configured for the target Node in NNMi's Communication Configuration settings (without your needing to provide any in the MIB Browser).
- Enter a valid read community string for the Node.
Version (optional): Do one of the following:
- Leave this attribute value blank. NNMi uses the SNMP version currently configured for the target Node in NNMi's Communication Configuration settings (without your needing to provide any in the MIB Browser).
- Select an SNMP version from the drop-down list.
For a discovered Node: NNMi uses the read community string, SNMP version, timeout, maximum retries, and management address port currently configured for the target Node in NNMi's Communication Configuration settings for that Node (without your needing to provide any of those values in the MIB Browser).
For an undiscovered Node: NNMi uses default timeout, maximum retries, and management address port parameters provided by the NNMi administrator within the nms-ui.properties file. And you must type a value in the MIB Browser's Read Community String field.
OID: The MIB's object identifier (number or mnemonic keywords) you want to use for gathering one value or multiple values with the SNMP Walk:
If you access MIB Browser using Tools → MIB Browser = the default value is.iso.org.dod.internet.mgmt.mib-2.system
If you access MIB Browser using MIB Information → MIB Browser = NNMi populates this attribute with the currently selected view's row or form's MIB Variable value.
- Numbers must begin with a dot (.)
- As you type, a list appears assisting with auto-complete possibilities (OID text, numeric, or alias).
- Click the MIB Tree icon to select the OID of interest. Click one of the following:
  OK = Populates the OID field with the selected value.
  Clear = Deletes any text from the OID field.
  Cancel = Closes the MIB Tree popup.
  The items in the MIB Tree represent all MIB files currently placed in the required location on the NNMi management server's hard drive and Loaded for use. Each MIB Variable may or may not be available on the Node you querie.
- In the results pane, select a row, then Right-Click → Populate Current OID.
- Click Tools → OID Aliases to use a shortcut defined by an installed MIB fileManagement Information Base files are the basic building block of SNMP communication protocol. SNMP Agents are configured to respond to requests defined by a group of supported MIB files. (source text files). See also Use Aliases in MIB Browser Commands.
The Node's SNMP Agent .responds to .1.3 with a list of real-time values for all currently supported MIB variables. See also MIB Variables View for more ideas.
To see the Node's response to the MIB Browser's request:
- Press Enter or click the SNMP Walk button to get SNMP Walk results from your starting point down though the MIB Variables tree.
- Click the Stop Walk button to suspend the operation. (If the text on this button is gray, all data has been collected.)
If you are gathering SNMP data from a Node that is not currently in the NNMi database, notify your NNMi administrator that SNMP communications with this Node is possible, but not currently configured in NNMi. Request that your NNMi administrator establish Communication Configuration settings for automatic SNMP communication with this Node.

Use Aliases in MIB Browser Commands

The MIB Browser uses the MIB Variable you enter into the OID attribute to determine which information is gathered or changed on the target Node. Type that OID value in one of the three formats specified in the MIB File's definition of that MIB Variable:

The numeric identifier
The text string identifier
The alias (short text string)

To understand which particular alias values could save you time, do the following:

Navigate to the MIB Variables View.
Right-click the Syntax column heading and select Filter → Create Filter.
Configure the filter with Equals = Other. Click Apply. The rows now visible in your MIB Variables view are the alias values provided by the MIB Files that are currently loaded onto the NNMi management server.
To reduce the list to only those aliases for a particular MIB or MIBs of interest, create a filter for the MIB column.
Double-click each row to study the definition and understand what the alias can do for you.
Now you can access the MIB Browser and copy/paste or type those aliases into the OID attribute to configure your query when you do the following:
- Run SNMP Walk Commands (MIB Browser)
- Run SNMP Set Commands (MIB Browser)
In the MIB Browser, the Tools → OID Aliases menu item displays a quick-reference list of all available MIB aliases currently loaded on the NNMi management server.
