Simple Network Management Protocol (SNMP) is an application layer protocol that performs network management operations over Ethernet using the User Datagram Protocol/Internet Protocol (UDP/IP). With SNMP, administrators can query the library for information (configuration, operation, statistical) and the library can inform administrators of potential problems. The library can also send information to a StorageTek Tape Analytics (STA) server (for more information, see the STA documentation on OTN).
SNMP v3 — Both read and write support. Transmitted information is secure.
SNMP v2c — Read-only support primarily for machine status queries. Transmitted information is not secure.
Note:
Configuringpublic
or private
as valid community strings is a major security risk.Either SNMP v2c or SNMP v3 can retrieve object IDs in the MIB file and send traps to the trap recipient list. However, because SNMP v3 provides encryption capabilities and stronger user identification, you can change library properties only with SNMP v3.
Configure firewalls to allow communications over these ports:
161 — For transmittal of SNMP requests to read the MIB.
162 — For reception of SNMP traps (notifications of device problems, errors, or significant events).
Library firmware:
SL8500 version FRS_3.12 or higher
SL3000 version FRS_1.7 or higher
SL150 version 1.0 or higher
Note:
STA has separate firmware requirements. See the STA documentation for more information.SLC version FRS_4.0 or higher.
SNMP must be enabled on the library.
You can configure SNMP through the following methods:
SL3000 and SL8500 — CLI (see Chapter 4, "Configuring SNMP with the CLI").
SL150 — Browser user interface with user role of either administrator or service (see the SL150 User's Guide).
