D: Snmp; Overview - StorageTek L180 Installation Manual

SNMP
This appendix describes the implementation of the Simple Network
Management Protocol (SNMP) for the L180 Tape Library.

Overview

StorageTek's L-series library embedded agents support Version 1 of the SNMP
standard (SNMPv1). SNMP is an application layer protocol that performs
network management operations over an Ethernet connection using a User
Datagram Protocol (UDP/IP).
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.
System administrators and network managers use SNMP to monitor and receive
status from the library, such as:
• Operational state of the library (microcode level, serial number, online)
• Status of the cartridge access port (open or 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 tape drives installed in the library
• Plus many other variables defined in the database (MIB)
