Introducing PowerDsine PowerView 2 Introducing PowerDsine PowerView PowerDsine PowerView is a management system for complete monitoring and control of PowerDsine's Power over LAN (PoL) Midspans, via an SNMP manager or remote network management station. The system provides direct, on-line power supervision, configuration, monitoring and diagnostics of PowerDsine products, via their SNMP agents. 2.1 Overview 2.2 Features PowerDsine PowerView provides a number of unique features for PoL Midspan management: ! ! ! ! ! ! ! ! ! Web-based application for remote management of Power over LANTM devices SNMP management capabilities for network element management Configuration using graphical representations of remote device Real time monitoring with visual status indicators and alarms Events and performance data recording using trap log System status display Real time power parameters, in a flowing graph mode Optional DHCP enabled-client Runs on a PC platform with Windows graphic user interface (GUI). 2.3 System Capabilities PowerDsine PowerView can be installed on any PC on the Local Area Network, providing remote management capabilities of Power over LAN devices connected to the LAN. PowerDsine PowerView allows for monitoring and controlling at two separate levels, as shown in Figure 2-1: ! ! Network level Element level. Version 2.1 7 March 2003 SNMP Figure 2-1: Management Deployment 2.3.1 Network Level PowerDsine provides network management capabilities to monitor and control an array of Power over LAN Midspans. The system is compatible with MIB management platforms, including HP Openview and SNMPc. 2.3.2 Element Level Element management is performed at unit and port levels. At unit level, parameters can be retrieved directly to the Power over LAN Midspan. These are: product identification, active power source, product status and unit power consumption. Parameters at port level include: maximum per port power, port priority level, port status and type of powered device connected. 2.4 Security Security is implemented in PowerDsine PowerView on three levels: SNMP security - handles the entire SNMP communication process by the community field. User privately-implemented security ­ The User can specify the access level of each and every employee. Password protection ­ the User is required to enter a password 3 to 10 alphanumeric characters long. Power over LAN Solutions 8 Catalog Number: 06-6910-056 Web Manager User Guide 2. Introducing PowerDsine PowerView 2.4.1 SNMP Security Community strings provide a basic form of access control in SNMP v2 (PowerDsine PowerView is based on SNMP v2). Whenever a community string is defined, it must be provided along with any basic SNMP query, if the requested operation is to be permitted by the device. Community strings usually allow read-only or read-write access to the entire device. SNMP community authentication is part of the setup for the server. The authentication can be changed by the user, via a console and via a Web browser. In the absence of additional configuration options to constrain access, knowledge of the single community string for the device is all that is required to gain access to all objects, both read-only and read-write, and to modify any read-write objects. 2.4.2 User Authentication PowerDsine PowerView employs user-type authentication in order to verify the identity of each user. The authentication is a type/password verification. An encrypted password is allocated for each user type. The program has defined several user types for the system. These users have a different role and, as such, have different access authorizations. Each user type is allocated a different scope of access control. Access definitions per user, are listed in Table 2-1. Table 2-1: User Authorizations USER TYPE · · · · AUTHORIZATION Can view relevant parameters of the PoL Midspan. Not allowed to change or add new parameters. Can view pertinent information on the system, including online alerts. May change his password. Operator Supervisor · Acts as an operator. · Can view and edit SNMP MIB2 information. · Can change the configuration of Units and Ports. · · · · Acts as a supervisor. Can update software . Can perform remote system reset Change SNMP parameters: * Community authentication for SNMP agents * Polling interval * Polling timeout * Polling retries Administrator Version 2.1 9 March 2003 SNMP Reader's Notes Power over LAN Solutions 10 Catalog Number: 06-6910-056 Web Manager User Guide 3.

Version 2.1 29 March 2003 SNMP 4.6 Viewing Trap Log Entries 4.6.1 About Traps Recording PowerDsine PowerView includes an internal SNMP trap handler which records SNMP traps addressed to it. A trap is sent when the status of a device changes. Traps are unsolicited messages, such as a port sensing its PD was disconnected or main AC power switching to standby (DC power source). Figure 4-7 displays a number of traps recorded by the application program. The individual trap listings compose a file started the moment PowerDsine PowerView initates the connection between the PoL unit agent and the SNMP manager. File content is limited to 5000 messages. Once the connection is terminated, this log file is erased. The operator can choose to copy the file at any time. Note Communication problems of the managed device with the manager will be indicated by Red error messages. Figure 4-7: Trap Log Panel 4.6.2 Definitions Date: the day and time the message was received from the agent and logged. Node: describes the IP address of the device reporting the message.
