SNMP Profile Default SNMP Parameters(3.0)

The SNMP Request agent uses the CSV files as information source to poll network elements. 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 in the profile:

Polling interval
Trap port

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)	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	Select the version. If no other value is defined in the CSV file of the SNMP Request agent, this value is 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 are defined in the CSV file of the SNMP Request agent, these settings are 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 defined in the network element. For more information about the SNMPv3, see SNMP_Wiki. If no other values are defined in the CSV file of the SNMP Request agent, these settings are 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. 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.
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 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.
