Agent Software
AT-View
In addition to the Omega agent, ATI also provides an optional network
management package called AT-View. This Windows-and/or UNIX-based
SNMP software application offers an easy-to-use and inexpensive graphical
user interface (GUI). AT-View is ideal for simple and fast diagnostics, as well
as for configuration and the monitoring of network devices.
Specifically, AT-View allows you to perform such network monitoring and
management tasks as:
❑
Assign names to hubs, modules, and/or ports
❑
Identify enabled/disabled ports
❑
Change the enabled/disabled status of ports
❑
Configure polarity correction
❑
Set reconnect algorithms
❑
Enable/disable link test
AT-View provides the tools to monitor your network’s health by tracking 20
current network statistics, including total collisions and errors. AT-View’s
GUI toolkit also offers critical parameter graphing capability that facilitate
the tracking of network performance trend lines.
Boot Protocol (BootP)
BootP is a protocol utility designed to automatically detect and recognize
diskless workstations. The function of the BootP utility within an IP server is
to enter an IP address into the repeater. That is, since all SNMP devices
require an IP address if they are to be managed, environments that do not
have BootP require you to enter the IP address manually.
BootP is covered under RFC 951 and includes the following requirement:
“In the case of clients who do not know their IP addresses, the server must
also have a database relating hardware addresses to IP addresses. This client
IP address is then placed into a field in the boot reply.”
This RFC as well as other related RFC’s can be found on the anonymous FTP
server NIS.NSF.NET in ATI’s documents\rfc directory.
The options for configuring an IP address are Omega and BootP. With Omega,
the unit will not send BootP requests once the unit has the IP address
configured.
The process is straightforward. If an IP address has NOT been configured for
a unit (for example, if Omega was used through the console port), then the
system will transmit a BootP request packet approximately every three
seconds until a response is received (up to a maximum of three request
attempts).
If a BootP response is NOT received, the system will continue to operate with
either the configured IP address, if an IP address was configured, or with a
computed pseudo IP address (if an IP address was not configured). A pseudo
IP address — a computed number based on the unit’s MAC address — allows
the system to be managed in non-IP networks (e.g., Novell) without requiring
you to either know or maintain an IP address.
