MIB Workspace

Load

Select the MIB files you want to load and use to build the target UDR. These types of files are often defined with the extension .mib by the vendors, but there is no naming convention and it can be anything.

Unload

Select the MIB file you want to unload and click this button.

Unload All

Click this button to unload all MIB modules.

Expand All

Click this button to expand all MIB tree branches.

MIB Object Properties

This panel shows the properties of the selected MIB file.

SNMP Query Results

OID

Object Identifier of the currently selected MIB Object. This OID is used to send out SNMP requests to remote network element for testing purposes.

VALUE

The Value field is used to specify the value of the SNMP SET operation, which you can edit. The value must follow the syntax and semantics of the selected MIB Object. This field is also used to populate the result of the SNMP Get command, which is grayed out and cannot be edited.

SNMP GET

Performs SNMP GET operations on the selected MIB object.

SNMP GET-NEXT

Performs SNMP GET-NEXT operations on the selected MIB object.

SNMP GET-BULK

Performs SNMP GET-BULK operations on the selected MIB object.

SNMP WALK

Walks the selected MIB tree branch and retrieves all values.

SNMP SET

Performs SNMP SET operations on the selected MIB object. Specify the value to be set in the Value field.

STOP

Stops the current SNMP operation.

CLEAR

Clears the SNMP results area.

General

Host

Define the host used to perform SNMP queries for testing purposes directly from the MIB workspace tab. This value is optional since the hosts should be defined in the CSV file of the SNMP Request agent.

Polling Interval (ms)

The default polling interval for SNMP is 300 seconds. This value is used if no other value is defined in the CSV file of the SNMP Request agent. The value must always be set here, it can not be set in the input CSV file.

Polling Distribution Period (ms)

This field is used to configure how long the distribution period should be in milliseconds (ms). By default this field is set to zero ("0"), meaning that no distribution period is configured, and polling will be distributed evenly over the polling interval. If you configure the distribution period, the polling will be distributed within this period only during the polling interval, meaning the distribution period has to be equal to, or shorter than, the polling interval. The distribution period will start at the beginning of the polling interval.

Port

Default port for SNMP is 161. If no other value is defined in the CSV file of the SNMP Request agent this value is used.

Trap Port

Default trap port for SNMP trap is 162. This value is used by the SNMP Trap agent to listen for incoming SNMP notifications (TRAPs and INFORMs). This value must always be set here.

SNMP Version

SNMPv1

Use read and write communities to access the network element via SNMPv1. 

SNMPv2c

Use read and write communities to access the network element via SNMPv2c. For more information about the SNMPv2c, see SNMP_Wiki. 

Read Community

The “SNMP community string” is like a user ID or password that allows access to a target network element. The read community is used for GET, GET-NEXT, and GET-BULK requests.

Write Community

The “SNMP community string” is like a user ID or password that allows access to a target network element. The Write community is used for SET requests.

SNMPv3

Use the same parameters and authentication as defined in the network element. For more information about the SNMPv3, see SNMP_Wiki. 

User Name

The principal on whose behalf access is requested. This must be a human-readable string representing the user in a format that is Security Model independent.

Context Name

The collection of management information accessible by an SNMP entity.

Context Engine ID

An SNMP engine provides services for sending and receiving messages, authenticating and encrypting messages, and controlling access to managed objects. There is a one-to-one association between an SNMP engine and the SNMP entity which contains it. Within an administrative domain, an EngineID is the unique and unambiguous identifier of an SNMP engine. Context Name - the name of an SNMP Context.

Auth Protocol

The authentication protocol that is used to authenticate the user. Four protocols are defined: SHA-2 224, SHA-2 256, SHA-2 384, and SHA-2 512.

Auth Password

The password required for authentication service.

Priv Protocol

The privacy protocol that is used to protect the message from disclosure. Two such protocols are defined: DES-CBC Symmetric Encryption Protocol and CFB-AES-128.

Priv Password

The password required for privacy (encryption) service.

Request Handling

Timeout (ms)

The timeout is the time interval that the SNMP Request agent waits for a response message from the target network element. The timeout value is given in milliseconds.

UDR Timeout (ms)

UDR Timeout in milliseconds. If the time exceeds the timeout, the UDR will be sent on the next route.

Number of Retries

Retries are the number of times a SNMP request is sent when a timeout occurs. If the retry value is zero (0), the request is not re-transmitted during timeout.

Max Outstanding Per Element

The maximum number of simultaneous outstanding requests per element allowed. When this limit is reached, no new requests are sent to the element until responses for the outstanding requests are received. The default value is set to zero (0), which means that no limit is set and any number of simultaneous outstanding requests is allowed.

General

Max PDU Size

The maximum size of request PDUs that this target is able to receive.

The response PDU has to fit in a single UDP packet. The maximum limit is 65535 bytes.

Get-Bulk Parameters

Non Repeaters

Number of variables in the variable list for which a simple GETNEXT operation has to be done. 

Max Repetitions

Number of continuous GETNEXT operations.

Scalar Value Retrieval

Max Variables Per PDU

The maximum number of variable bindings per request.

Table Retrieval

Max Columns Per PDU

Maximum number of columns to retrieve per SNMP GETNEXT or GETBULK request.

Max Rows Per PDU

Maximum number of rows to retrieve per SNMP GETBULK request.

Send Table Requests in Separate PDUs

By default all column OIDs from a single table are now sent in one GETBULK request in accordance with the Max Variables Per PDU. Use this if All column OIDs from a single table are to be sent in separate GETBULK requests.
