Solution 1999372.1 : FS System: How to Generate and Test SNMP Traps

Applies to:

Oracle FS1-2 Flash Storage System - Version All Versions and later
Information in this document applies to any platform.

Goal

This document provides the steps to generate an SNMP trap on the FS1-2 System and trace it on a configured host, using either the GUI or the CLI.

Solution

The Simple Network Management Protocol (SNMP) trap facility can be configured on the FS1-2 to send traps to configured hosts. Any workstation that has an SNMP-based management application installed on it can be a trap host. For further details, refer to the section "SNMP Trap Host Management" in the Oracle Flash Storage System Administrator's Guide.

Note: The FS1-2 also performs (GET) SNMP v2 functionality via MIB interface (not detailed here).

Configuring SNMP Using the GUI

Navigate to System > Global Settings > SNMP.
Select Actions > Create.
Enter a Name for the SNMP host.
Enter the values in the Host IP field and the Community String field to specify where the traps are directed. The community string must contain at least six characters.
Select the Receive traps option to enable the Trap Port Number field.
Enter the Trap Port Number. For SNMP traps, use port 162.
(Optional) Select the Severity threshold from the list of possible filters:
- Informational: Requires no action for events that are information only.
- Warning: Requires no immediate action for minor conditions that you can address at your convenience.
- Critical: Requires prompt action to prevent system failures or offline conditions.
Click OK.

Configuring SNMP Using FSCLI

For details, refer to the Oracle Flash Storage System CLI Reference.

Syntax:

snmp_host { [ ‑add | ‑delete | ‑list | ‑modify ] | [ ‑usage | ‑help ] }

Example:

$ fscli snmp_host ‑add ‑name snmp_trap_server_1 ‑ip 192.168.10.5 ‑community public ‑trapPort 162 ‑trapEvent warning

Generating a Test Trap

Any add, delete, or modify of the SNMP settings will send a trap to a configured SNMP host. On the host, trace on the configured UDP port (usually 162). Examples are shown below for Solaris and Linux. For a complete list of supported operating systems, refer to the Oracle Flash Storage Support and Interoperability Guide.

Note: Ensure your snoop or tcpdump is monitoring on the required physical network interface.

On Solaris use snoop. For example:

# snoop -x0 udp port 162

1   0.00000 fs1-2-pilot1 -> myhost-dom00 UDP D=162 S=50699 LEN=190

On Linux use tcpdump. For example:

# tcpdump -vv udp port 162

12:55:05.418770 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto UDP (17), length 210)
