Configuring Your Library
You cannot enable the SSL settings from the Web client. The path to open the appropriate screen is as follows:
From the operator panel, select Tools > System Settings > Enable SSL.

Configuring SNMP Settings on the Library
SNMP is a light-weight protocol designed for remote management and monitoring of infrastructure devices. The library
provides SNMP support, so an external management application can be configured to receive library SNMP information. The
library supports SNMP by publishing a Management Information Base (MIB) that can be queried to obtain the status of the
library and many of its individual components. SNMP information can be obtained from the library using SNMP Traps and GET
queries.
For more information about SNMP, see the Dell PowerVault ML6000 Basic SNMP Reference Guide. For information on
integrating MIBs with an SNMP management application, contact your network management application vendor.
Administrators can perform the following SNMP procedures:
•
Register the IP addresses and port numbers of external management applications, enabling them to receive SNMP
traps from the library. For more information, see
•
Enable or disable support for SNMP v1 and v2c. SNMP v3 is enabled by default and cannot be disabled. For more
information, see
•
Choose which version of SNMP the library uses to report traps. You can choose SNMPv1 or SNMPv2. The default is
SNMPv1.
•
Modify the default SNMP community string, which is used as a password to authenticate GET and GET-NEXT SNMP v1
and SNMP v2c messages exchanged between the library and a remote management application. For more information,
see
Modifying the SNMP Community
•
Enable or disable SNMP authentication traps, which are messages indicating an authentication failure. For more
information, see
•
Download the library MIB, which can be used to integrate the library with an SNMP management application. For more
information, see
Registering External Management Applications
Administrators can register transport protocols, IP addresses, and port numbers of external management applications to
enable them to receive SNMP traps from the library. (By default, the library ignores all SNMP SET operations, so external
management applications cannot register themselves to receive SNMP traps from the library.)
After registering the transport protocols, IP addresses, and corresponding port numbers, you can perform a test to verify that
the library can send the SNMP traps to the addresses.
When registering external management applications to receive SNMP traps, you can set the following parameters:
•
Transport — The transport protocol. This should be the same as the transport protocol configured on the SNMP trap
receiver. Select one of the following:
•
UDP/UDP6 — User Datagram Protocol. For IPv4, select UDP; for IPv6, select UDP6.
•
TCP/TCP6 — Transmission Control Protocol. For IPv4, select TCP; for IPv6, select TCP6.
•
Host Name/IP Address — The host name or the IP address of the external management application you want to
register. A host name may be entered only if DNS is enabled. Otherwise, IP addresses must entered. For information
on DNS, see
Modifying Network
Port — the port number of the external application you want to register. The default port number for an external
•
application is 162.
Create — Adds the IP address and port number of the external application to the list of registered addresses that will
•
be sent SNMP traps.
•
Delete — Allows you to delete a selected IP address and port number.
•
Test — Verifies only that the library has sent SNMP traps to all registered IP addresses. Check the external
applications to verify that the traps were received.
While the test is in progress, the Progress Window appears. If the test is successful, Success appears in the
Progress Window and the traps were successfully sent. If the test is unsuccessful, Failure appears in the Progress
Window. Follow the instructions listed in the Progress Window to resolve any issues that occur during the
operation.
