The SNMP Request agent uses the CSV files as the source of information regarding the network elements to poll. The parameter from the default set is used when the corresponding parameter is unspecified in the input CSV file this is valid for all parameters except two is in the profile:
- Polling interval
- Trap port
The SNMP profile - Default SNMP Parameters tab
| Field | Description |
|---|---|
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) | Default for SNMP is 300 seconds, in case no other value has been defined in the CSV file of the SNMP Request agent, this value will be used. This value must always be set here, it can not be set in the input CSV file. |
| Polling Distribution Period (ms) | This field can be used for configuring how long the distribution period in ms should be. By default this field has "0" set as value, meaning that no distribution period is configured, and polling will be distributed evenly over the polling interval. If you configure 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 for SNMP is 161, in case no other value has been defined in the CSV file of the SNMP Request agent, this value will be used. |
Trap Port | Default for SNMP trap is 162. Used by SNMP Trap agent to listen for incoming SNMP notifications (TRAPs and INFORMs). This value must always be set here. |
| SNMP Version | Select the version. If no other value has been defined in the CSV file of the SNMP Request agent, this value will be used. |
| 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 . If no other values have been defined in the CSV file of the SNMP Request agent, these settings will be used. |
| 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 you have defined in the network element. For more information about the SNMPv3, see SNMP_Wiki. If no other values have been defined in the CSV file of the SNMP Request agent, these settings will be used. Note! The parameters 'Retry' and 'Timeout' are not used as expected, this is due to an error in the underlying library used. 'Retry' is used during the discovery call, as well as the actual call when it should only be used during the actual call. 'Timeout' is not only used during actual timeouts, but between any Retry attempts. |
| Username | The principal on whose behalf access is requested. 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. Six protocols are defined: MD5, SHA-1, 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: the CBC-DES Symmetric Encryption Protocol and CFB-AES-128. |
| Priv Password | The password required for privacy (encryption) service. |
| 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. Note! This timeout must be set so that the following is true: "Polling Interval > Timeout * (Number of Retries +1)". This is checked when validating the SNMP profile. However, take care when using the CSV_TIMEOUT and CSV_RETRIES in the Network Element file. |
| UDR Timeout (ms) | UDR Timeout in milliseconds. If the time exceeds the timeout, the UDR will be sent on the next route. Note! This UDR timeout must be set so that the following is true: "UDR timeout > Timeout * (Number of Retries +1)". This is checked when validating the SNMP profile. |
| Number of Retries | Retries are the number of times a SNMP request is sent when a timeout occurs. If the retry value is 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 will be sent to the element until responses for the outstanding requests have been received. The default value is set to 0, which means that no limit is set and any number of simultaneous outstanding requests is allowed. |
