Management Stations
Management stations gather network data collected by Agilent probes. They
present this information in easy-to-use and easy-to-understand text and graphic
formats. You can use a management station to communicate with your probe after
it has been installed and configured.
The probe communicates with the NetMetrix software running on your
management station. NetMetrix management applications allow you to review
and reconfigure the probe parameters (such as IP address, trap destinations, filters,
and packet captures), to manage the information collected by the probe (including
statistics, historical studies, alarms, and captured packet traces), and to monitor
local or remote networks (by gathering network statistics from Agilent Probe
agents as network monitors).
Refer to your NetMetrix documentation for more information.
Access Security
The probe’s configuration menu allows network administrators to disable standard
RMON functions which could be considered a security risk. The security menu
allows network administrators to disable the RMON-1 packet capture capabilities
of the probe to prevent network users from viewing network traffic. TFTP
firmware downloads can be disabled to prevent users from downloading earlier
versions of the probe firmware which did not support these new security features.
For more information, refer to “Modify/View Security Values” on page 24.
The probe’s private MIB uses a four-level access control scheme. An access level
is assigned for each community string to be used with the probe. The access level
is an integer value between one and four, with increasing degrees of authorization
granted for higher authorization numbers. Each higher level is granted the rights
of all lower levels in addition to the specific privileges of that level. Table 1-1 on
page 9 shows specific access privileges by level.
