1 SNMP Overview and Requirements

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).

Supported SNMP Versions

  • 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:

    Configuring public 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.

SNMP Ports

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).

SNMP Configuration Requirements

  • 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.

SNMP Configuration Methods

You can configure SNMP through the following methods:
