Installation and Operations Manual
SNMP/Thresholds
The PT22 supports the Simple Network Management Protocol (SNMP). This allows network
management systems to use SNMP requests to retrieve information and control power for the individual
outlets.
The unit includes an SNMP v2c agent supporting standard MIB I and MIB II objects. A private
enterprise MIB extension (Sentry3 MIB) is also supported to provide remote power control.
For more information about enabling and configuring SNMP, see the SNMP section in this manual.
NOTE: The default for SNMP support is Enabled. When Server Technology products are shipped, the default SNMP
configuration for the GET community string is set to “public” and the SET community string is left blank. You will need
to restart the PT22 after enabling or disabling SNMP support
About SNMP Versions
The firmware supports SNMP versions 1, 2, and 3.
SNMP version 3 supports authentication and encryption on a per user basis. Authentication types are
None and MD5. Encryption types are None and DES. If you use authentication, you must use
encryption.
Two SNMPv3 users are supported: one user with read-write (RW) access, and one user with read-only
(RO) access Both users have the same configuration parameters, and you can configure each user
independently.
SNMPv2 and SNMPv3 can be enabled or disabled independently. You can have SNMPv2 and/or
SNMPv3, or none.
SNMP CLI Commands:

All SNMP v3 specific configuration settings use the CLI command SET SNMP V3.
 All SNMP v1/v2 specific configuration settings use the CLI command SET SNMP V2.
 All SNMP configuration settings common to any SNMP version use the CLI command
SET SNMP.
NOTES:
 If you use SNMP v1 or SNMP v2, all SET SNMP CLI commands (and the SHOW command) require the “V2”
keyword.
 SNMP v1/v2 CLI commands are documented immediately below in this section showing the required “V2” keyword.
All CLI commands that follow the SNMP v1/v2 section in this manual assume SNMP v3.

Enabling and Setting Up SNMP v1/v2 Support
SNMP v1/v2 support must be enabled and configured for access to Sentry3 MIB objects and generation
of all Sentry3 traps.
Enabling/disabling SNMP support:
The SNMP Set command is used to enable or disable SNMP v1/v2 support.
