By default, most SNMP information is returned as an integer value (library partition names, however, are returned as string values). For instance, the return value of Library Main Door might be 2, which indicates that the library door is closed. You can, however, configure the framework application to return status information as a string value, which provides a description of the status. For example, the return value of Library Main Door might be closed(2). To do this, you must compile and integrate the library's MIBs with your framework application. SNMPv3 Although the ML6000 library supports SNMP version 1 and version 2c for MIB information retrieval, we strongly recommend that you access the library using SNMP version 3 (SNMPv3). SNMPv3 is the most secure of the three versions, as it supports message digest 5, or MD5, as its authentication protocol. To access the library for SNMP support, use the following values as needed in the remote management application: User name: Admin Context name: (None. Leave this field blank.) Authentication protocol: MD5 Privacy protocol: (None. Leave this field blank.) Password: Your Admin password For secure access to the library using SNMP, disable SNMPv1 and SNMPv2c access from the remote Web client and the operator panel. For more information, see either the Dell PowerVault ML6000 Tape Library User's Guide or the relevant ML6000 online help topics. SNMP Traps Traps enable alerts to be sent automatically to registered hosts when specific events occur. Only one application per UDP port can listen for traps. The ML6000 library supports SNMP v1 and v2 traps as defined by RFC 1157. You can set the library to report SNMP traps using either v1 or v2 (v1 is the default). The timeout for all SNMP requests to the library must be at 10 seconds or greater (command line parameter-t). To receive traps, you must perform two steps: 1 Configure your framework application to collect traps from the ML6000 library. 2 Using the library's SNMP Trap Registrations feature, register the host's IP address, transport protocol, and UDP port number. Registration informs the ML6000 library to send traps to the host. For additional details about registering a host with the ML6000 library, refer to the PowerVault ML6000 Tape Library User's Guide. SNMP Queries SNMP queries, or GET queries, can be initiated on a periodic basis by the framework application. By querying the MIB, hosts can gather status information about specific components of the library. Frequent MIB queries are not required, however, since the SNMP agent is event-driven. 4 Description

Description
By default, most SNMP information is returned as an integer value (library partition names, however, are
returned as string values). For instance, the return value of
Library Main Door
might be 2, which indicates
that the library door is closed.
You can, however, configure the framework application to return status information as a string value, which
provides a description of the status. For example, the return value of
Library Main Door
might be
closed(2)
.
To do this, you must compile and integrate the library’s MIBs with your framework application.
SNMPv3
Although the ML6000 library supports SNMP version 1 and version 2c for MIB information retrieval, we
strongly recommend that you access the library using SNMP version 3 (SNMPv3). SNMPv3 is the most
secure of the three versions, as it supports message digest 5, or MD5, as its authentication protocol.
To access the library for SNMP support, use the following values as needed in the remote management
application:
User name:
Admin
Context name:
(None. Leave this field blank.)
Authentication protocol:
MD5
Privacy protocol:
(None. Leave this field blank.)
Password:
Your Admin password
For secure access to the library using SNMP, disable SNMPv1 and SNMPv2c access from the remote Web
client and the operator panel. For more information, see either the
Dell PowerVault ML6000 Tape Library
User’s Guide
or the relevant ML6000 online help topics.
SNMP Traps
Traps enable alerts to be sent automatically to registered hosts when specific events occur. Only one
application per UDP port can listen for traps.
The ML6000 library supports SNMP v1 and v2 traps as defined by RFC 1157.
You can set the library to report SNMP traps using either v1 or v2 (v1 is the default). The timeout for all
SNMP requests to the library must be at 10 seconds or greater (command line parameter-t).
To receive traps, you must perform two steps:
1
Configure your framework application to collect traps from the ML6000 library.
2
Using the library’s
SNMP Trap Registrations
feature, register the host’s IP address, transport protocol,
and UDP port number.
Registration informs the ML6000 library to send traps to the host.
For additional details about registering a host with the ML6000 library, refer to the
PowerVault ML6000
Tape
Library User’s Guide
.
SNMP Queries
SNMP queries, or GET queries, can be initiated on a periodic basis by the framework application. By
querying the MIB, hosts can gather status information about specific components of the library. Frequent
MIB queries are not required, however, since the SNMP agent is event-driven.
