Advisory: HPE ProLiant Gen9 Servers - "hp-snmp-agent" Does Not Send an SNMP Trap If The Target Peer is Not Running
NOTICE: The information in this document, including products and software versions, is current as of the Release Date. This document is subject to change without notice.

Release Date: 2017-12-07

Last Updated: 2017-12-07


On an HPE ProLiant Gen9 server running a Red Hat or SUSE Linux OS, using hp-snmp-agent versions 10.4.0, 10.5.0, 10.6.0 or 10.6.1, the hp-snmp-agent may not send an SNMP trap if the target peer is not running.

Note: The tcpdump confirms that no trap was sent to the system.

This occurs because the communication daemon under the hp-snmp-agent may receive a FiFO overflow error from the target peer channel, which causes the trap to drop. If the target peer is not running, hp-snmp-agent saves unsent SNMP trap into a unsent trap list. The host daemon will try to send the unsent SNMP trap again when doing the next polling. In some cases, hp-snmp-agent ignores to save unsent SNMP trap into the list, which is unnecessary.


Any HPE ProLiant Gen9 server running a Red Hat or SUSE Linux OS, configured with an HPE Smart Storage Battery and using hp-snmp-agent versions 10.4.0, 10.5.0, 10.6.0 or 10.6.1.


To resolve this issue, upgrade the hp-snmp-agent to version "hp-snmp-agent-10.6.2" (or later). This software adds a re-send mechanism to retry the delivery of an SNMP trap. This hp-snmp-agent version is available on the HPE Support Center.
