ONITORING ECHNOLOGY
From a network management console, traditional network management
applications poll network devices such as switches, bridges, and routers
at regular intervals. The console gathers statistics, identifies trends, and
highlights network events. The console polls network devices constantly
to determine if the network is within its normal operating conditions.
As network size and traffic levels grow, however, the network
management console can become overburdened by the amount of data
it must collect. Frequent console polling also generates significant
network traffic that itself can create problems for the network.
An RMON implementation offers solutions to both of these problems:
The RMON probe examines the network without affecting the
characteristics and performance of the network.
The RMON probe reports by exception rather than by gathering
constant or frequent information. That is, the RMON probe informs
the network management console directly if the network enters an
abnormal state. The console can then use more information gathered
by the probe, such as historical information, to diagnose the abnormal
condition.
CoreBuilder 2500 Extended Switching software offers full-time
embedded RMON support using SNMP for seven of the RMON groups.
When combined with the Roving Analysis Port (RAP) function, RMON
support for these groups provides a comprehensive and powerful
mechanism for managing your network.
You can gain access to the RMON capabilities of the CoreBuilder 2500
system only through SNMP applications such as Transcend
Manager software, not through the serial interface or telnet. For more
information about the details of managing 3Com devices using RMON
and Transcend tools, see the user documentation for the Transcend
Enterprise Manager software.
