These fields are automatically assigned when using the DHCP server or Client mode of
operation and are generally required when utilizing a Static IP address setting.
The controller provides configurable community strings for SNMP traps and Sets and
Gets.
Trap Community
Strings Individual IP addresses and description configurations for up to four
public community string alarm traps are provided. Assignment of
alarms to the appropriate community string is performed at the
Settings Communication Alarm Notification link.
Set/Get Community
Strings IP addresses and descriptions for up to three Set/Get community
strings are provided. Default community string descriptions are public,
public-write, and private. Each string has the ability to be configured
by an administrator to be write enabled or read only. The public-write
and private have been defaulted with write capability.
HTTP
HTTP (hypertext transfer protocol) is the foundation protocol of the World Wide Web (www)
and can be used in any client-server application involving hypertext. HTTP makes use of TCP
(transmission control protocol) for client to server connection and IP (internet protocol) for
internetworking. The Pulsar Edge’s standard HTTP protocol web pages provide integrated site
information with an enhanced graphical user interface. The on-board HTTP web pages server is
password protected for read/write privilege. Further access restrictions can be implemented using
the software read/write disable capabilities. The Pulsar Edge has a configurable timeout for
connections that remain idle more than a user-programmed time period. The best way to learn the
web pages is to go through each tab and look at the features.
TELNET
Telnet provides remote log-on capability to a computer or server. The terminal to terminal
connection with Telnet is based on a TCP connection for traffic between user and server. Once
login is established; the Pulsar Edge will support this session until the “exit” command is
received or the idle timeout limit is reached. A command line interface is used to view and
configure the Pulsar Edge’s features and thresholds. Backup, restore, and upgrade procedures
may also be performed.
SNMP
SNMP (simple network management protocol) is the most dominant network management
standard. It allows communication and control via open standards host systems for centralized
management of multiple plants. A number of vendors such as HP OpenView, IBM NetView,
Lucent OneVision, and Sun Micro’s NetManager have adopted the standard for
telecommunication and computer equipment network management. A standard MIB for the
Pulsar Edge is available to be down loaded on the web at
www.lineagepower.com . Up to four
SNMP alarm trap destinations can be programmed using the Network Settings link found in
Settings Tab of the web pages. Alarms then can be assigned under Alarm Notification also found
in the Settings tab of the web pages. SNMP is more fully described in the Appendix.
SMTP
SMTP (simple mail transfer protocol) provides a basic electronic email facility. It provides a
