Device Management Features SNMP Alarms and Trap Logs The system logs events with severity codes and timestamps. Events are sent as Simple Network Management Protocol (SNMP) traps to a Trap Recipient List. For more information on SNMP Alarms and Traps, see "Configuring LLDP and LLDP-MED" on page 181. SNMP Version 1 and Version 2 Simple Network Management Protocol (SNMP) over the UDP/IP protocol. To control access to the system, a list of community entries is defined, each of which consists of a community string and its access privileges. There are 3 levels of SNMP security; read-only, read-write, and super. Only a super user can access the community table. SNMP Version 3 Access to the switch using SNMPv3 provides additional security features that cover message integrity, authentication, and encryption; as well as controlling user access to specific areas of the MIB tree. The SNMPv3 security structure consists of security models, with each model having it's own security levels. Web Based Management With web based management, the system can be managed from any web browser. The system contains an Embedded Web Server (EWS), which serves HTML pages, through which the system can be monitored and configured. The system internally converts web-based input into configuration commands, MIB variable settings and other management-related settings. Configuration File Download and Upload PowerConnect device configuration is stored in a configuration file. The Configuration file includes both system wide and port specific device configuration. The system can display configuration files in the form of a collection of CLI commands, which are stored and manipulated as text files. For more information, see "Managing Files" on page 220. Trivial File Transfer Protocol (TFTP) The device supports boot image, software and configuration upload/download via TFTP. Remote Monitoring Remote Monitoring (RMON) is an extension to SNMP, which provides comprehensive network traffic monitoring capabilities with support for 64 bit counters (as opposed to SNMP which allows network device management and monitoring). RMON is a standard MIB that defines current and historical MAC-layer statistics and control objects, allowing real-time information to be captured across the entire network. For more information, see "Viewing RMON Statistics" on page 389. 20 Introduction

Introduction
Device Management Features
SNMP Alarms and Trap Logs
The system logs events with severity codes and timestamps. Events are sent as Simple Network
Management Protocol (SNMP) traps to a Trap Recipient List.
For more information on SNMP Alarms and Traps, see "Configuring LLDP and LLDP-MED" on
page 181
.
SNMP Version 1 and Version 2
Simple Network Management Protocol (SNMP) over the UDP/IP protocol. To control access to the
system, a list of community entries is defined, each of which consists of a community string and its
access privileges. There are 3 levels of SNMP security; read-only, read-write, and super. Only a super user
can access the community table.
SNMP Version 3
Access to the switch using SNMPv3 provides additional security features that cover message integrity,
authentication, and encryption; as well as controlling user access to specific areas of the MIB tree.
The SNMPv3 security structure consists of security models, with each model having it’s own security levels.
Web Based Management
With web based management, the system can be managed from any web browser. The system contains
an Embedded Web Server (EWS), which serves HTML pages, through which the system can be
monitored and configured. The system internally converts web-based input into configuration
commands, MIB variable settings and other management-related settings.
Configuration File Download and Upload
PowerConnect device configuration is stored in a configuration file. The Configuration file includes both
system wide and port specific device configuration. The system can display configuration files in the
form of a collection of CLI commands, which are stored and manipulated as text files.
For more information, see "Managing Files" on page 220.
Trivial File Transfer Protocol (TFTP)
The device supports boot image, software and configuration upload/download via TFTP.
Remote Monitoring
Remote Monitoring
(RMON) is an extension to SNMP, which provides comprehensive network traffic
monitoring capabilities with support for 64 bit counters (as opposed to SNMP which allows network device
management and monitoring). RMON is a standard MIB that defines current and historical MAC-layer
statistics and control objects, allowing real-time information to be captured across the entire network.
For more information, see "Viewing RMON Statistics" on page 389.
