Technical Note: How to configure ShelfManager to send SNMP trap V2 and not V1

[fgilloteau_FTNT]

Description

This article describes how to change the configuration of the Shelf Manager to send SNMP traps with SNMP v2.

Scope

PigeonPoint 3.4.2.2.

Solution

The Shelf Manager contains a file /etc/shelfman.conf with some variables that can be edited.  Any changes will be taken into account at the next reboot.

Use the local editor ‘vi’ to edit file.

The variable PET_SNMP_VERSION has a default value of ‘1’ (SNMP v1), this can be changed to ‘2’ (SNMP v2).

There is also an interesting variable ‘PET_FORMAT’ that can be changed from ‘0’ (default IPMI Platform Event Trap) to ‘2’ (multi variable format, each field is encoded as a separate variable defined in PPS-PET-MIB).  This will generate trap which is easier to read by a monitoring tool.

After this change, the Shelf must be rebooted for the value to be taken into account.

Note that rebooting the Shelf is a safe operation which should not affect the blades.
