SNMP

Introduction

The SNMP (Simple Network Management Protocol) service provides two different functions on the appliance:

Appliance status information can be served by SNMP. See MIBs.
Alerts can be configured to send SNMP traps.

Both SNMP versions 1 and 2c are available when this service is enabled.

Properties

Property	Description
SNMP community name	This is the community string that SNMP clients must provide when connecting
Authorized network	The network which is allowed to query the SNMP server, in CIDR notation. To block all clients, use 127.0.0.1/8 (localhost only); to allow all clients, use 0.0.0.0/0
Appliance contact	The string served by MIB-II OID .1.3.6.1.2.1.1.4.0. Setting this to a person or department's name will help SNMP clients determine who is responsible for this appliance
Trap destinations	The hostnames or IP addresses for sending SNMP traps to. Custom SNMP traps can be configured in the Alerts section. Set this to 127.0.0.1

Changing services properties is documented in the BUI and CLI sections of services. The CLI property names are shorter versions of those listed above. After changing properties, restart the SNMP service.

The SNMP service also provides the MIB-II location string. This property is sourced from the System Identity configuration.

MIBs

If the SNMP services is online, authorized networks will have access to the following MIBs (Management Information Bases):

MIB	Purpose
.1.3.6.1.2.1.1	MIB-II system - generic system information, including hostname, contact and location
.1.3.6.1.2.1.2	MIB-II interfaces - network interface statistics
.1.3.6.1.2.1.4	MIB-II IP - Internet Protocol information, including IP addresses and route table
.1.3.6.1.4.1.42	Sun Enterprise MIB (SUN-MIB.mib.txt)
.1.3.6.1.4.1.42.2.195	Sun FM - fault management statistics (MIB file linked below)
.1.3.6.1.4.1.42.2.225	Sun AK - appliance information and statistics (MIB file linked below)

Sun FM MIB

The Sun FM MIB (SUN-FM-MIB.mib) provides access to SUN Fault Manager information such as:

Active problems on the system
Fault Manager events
Fault Manager configuration information

There are four main tables to read:

OID	Contents
.1.3.6.1.4.1.42.2.195.1.1	Fault Management problems
.1.3.6.1.4.1.42.2.195.1.2	Fault Management fault events
.1.3.6.1.4.1.42.2.195.1.3	Fault Management module configuration
.1.3.6.1.4.1.42.2.195.1.5	Fault Management faulty resources

See the MIB file linked above for the full descriptions.

Sun AK MIB

The Sun AK MIB (SUN-AK-MIB.mib) provides the following information:

product description string and part number
appliance software version
appliance and chassis serial numbers
install, update and boot times
cluster state
share status - share name, size, used and available bytes

There are three main tables to read:

OID	Contents
.1.3.6.1.4.1.42.2.225.1.4	General appliance info
.1.3.6.1.4.1.42.2.225.1.5	Cluster status
.1.3.6.1.4.1.42.2.225.1.6	Share status

See the MIB file linked above for the full descriptions.

Tasks

The following are example tasks for SNMP. See the BUI and CLI sections for how these tasks apply to each interface method.

SNMP Tasks

Configuring SNMP to serve appliance status

Set the community name, authorized network and contact string.
If desired, set the trap destination to a remote SNMP host, else set this to 127.0.0.1.
Apply/commit the configuration.
Restart the service.

Configuring SNMP to send traps

Set the community name, contact string, and trap destination(s).
If desired, set the authorized network to allow SNMP clients, else set this to 127.0.0.1/8.
Apply/commit the configuration.
Restart the service.
