SNMP

This appendix provides the implementation of the Simple Network Management
Protocol (SNMP).
■Overview
Sun StorageTek’s L-series libraries support Version 1 of the simple network management
protocol (SNMPv1). SNMP is an application layer protocol that performs network
management operations over an Ethernet connection using a User Datagram Protocol
(UDP/IP). Library microcode 2.11 or higher supports SNMP.
SNMP allows systems administrators to query the library for configuration, operation,
and statistical information. SNMP also allows the library to inform the systems
administrator of potential problems.
Systems administrators and network managers use SNMP to monitor and receive status
from the library, such as:
• Operational state of the library (such as microcode level, serial number, online)
• Status of the cartridge access port (such as open, closed, number of cells)
• Library elements (number of hands, columns, panels, cells, CAPs)
• Number of storage cells and media types stored in the library
• Number and types of drives installed in the library
• Many other variables defined in the database
Figure A-1 on page A-2 illustrates a simple network block diagram that identifies the
locations of the SNMP software application, DNS servers, and Library Admin. This
figure also identifies the IP addresses, shows a map of DNS names (library names), and
other components involved in that configuration (such as operator panel, Ethernet
connections, location of the Management Information Base (MIB), and the LLC card.
