Dell EMC PowerFlex Rack Using PowerFlex Manager

SNMP communication

PowerFlex Manager can receive SNMP traps from system devices. It can forward SNMP traps to one or more remote network management systems.

PowerFlex Manager and the network management system use access credentials with different security levels to establish two-way communication. Review the access credentials that you need for each supported version of SNMP. Determine the security level for each access credential and whether the credential supports encryption.

To configure SNMP communication, you need the access credentials and trap targets for SNMP, as shown in the following table:

For SNMPv2 traps to send from a device to PowerFlex Manager, you must provide PowerFlex Manager with the community strings on which the devices are sending the traps. If during resource discovery, you selected to have PowerFlex Manager automatically configure iDRAC nodes to send alerts, you must enter the community string that is used in that credential.

For a network management system to receive SNMP traps from PowerFlex Manager, perform the following configuration outside of PowerFlex Manager:

• For SNMPv2 traps, you must provide the community strings to the network management system.
• For SNMPv3 traps, you must provide the PowerFlex Manager engine ID, user details, and security level to the network management system.

PowerFlex Manager supports different SNMP versions, depending on the communication path and function. The following table summarizes the functions and supported SNMP versions:

SNMP trap forwarding configuration supports multiple forwarding destinations. If you provide more than one destination, all traps coming from all devices are forwarded to all configured destinations in the appropriate format.

PowerFlex Manager stores up to 5 GB of SNMP alerts. Once this threshold is exceeded, PowerFlex Manager automatically purges the oldest data to free up space.
