About SNMP settings

Network management systems use SNMP (Simple Network Management Protocol) to monitor network-attached devices for conditions that require administrative attention. By configuring settings on the Logical Interconnect Groups and Logical Interconnects screens, you can enable third-party SNMP managers to monitor (read-only) network status information from the interconnects.

An SNMP manager typically manages a large number of devices, and each device can have a large number of objects. It is impractical for the manager to poll information from every object on every device. Instead, each SNMP agent on a managed device notifies the manager without solicitation by sending a message known as an event trap.

HPE OneView enables you to control the ability of SNMP managers to read values from an interconnect. You can filter the type of SNMP trap to capture, and then designate the SNMP manager to which traps will be forwarded. By default, SNMP is enabled with no trap destinations set.

When you create a logical interconnect, it inherits the SNMP settings from its logical interconnect group. To customize the SNMP settings at the logical interconnect level, use the Logical Interconnects screen or REST APIs.

Logical interconnect group and logical interconnect settings support SNMPv1, SNMPv2, and SNMPv3 protocols for forwarding traps, as well as for user read-only access to the interconnect management information base (MIB).

SNMPv3 provides a more secure administrative framework over the previous SNMP versions. You can enable SNMPv3 forwarding for trap and inform notifications, and define SNMPv3 users and multiple trap forwarding destination addresses using both IPv4 or IPv6 addresses. You are prompted to enter configuration settings when specifying trap forwarding destinations. The authentication protocols Message Digest 5 (MD5), Secure Hash Algorithm 1 (SHA1), and Secure Hash Algorithm 2 (SHA2) are supported. Privacy is ensured by either the Data Encryption Standard (DES) or the Advanced Encryption Standard (AES) methods of data encryption. Based on the security level, you define passwords for authentication and for privacy.

Migration for SNMPv3 functionality from Virtual Connect Manager (VCM) to HPE OneView is supported.
NOTE:

The engine ID of VCM SNMPv3 remote users associated with traps is migrated.
