CHAPTER 4
MONITORING AND MANAGING THE ATX
Monitoring your ATX consists of collecting and analyzing statistics
and status information. You can use LCM to gather some
information, but you need to use an NMS as your primary tool.
Managing your ATX consists of bringing modules on or offline,
disabling or enabling ports, setting the community name for the
ATX, and changing the console baud rate, all of which can be done
using LCM.
4.1 MONITORING STATISTICS
The ATX collects statistics that can assist you to build a
comprehensive profile of the traffic flow on each network, between
networks, to and from each end-node within your network, and
from outside your network. You can identify combinations of
source network, destination network, source end-node, destination
end-node, and protocol type for collection of traffic statistics. This
is made possible by the ATX’s multiple RISC processors.
Each ATX is capable of compiling statistics for all attached
networks and 8,192 end-nodes. You can use this information,
available through most SNMP-based NMSs, to analyze your
network traffic flow and to make configuration changes as
necessary. You can then head off potential bandwidth bottlenecks
before they occur.
The end-node information can help you identify nodes that require
high bandwidth and should be connected through a dedicated
connection, rather than a shared, network connection. It can also
help identify an end-node that is generating many multicast
packets due to a malfunction.
For a more detailed analysis, you can have the NMS combine
statistics for source network, destination network, source end-
node, destination end-node, and protocol type.
Statistics that apply to the ATX as a whole are described here and
the applicable MIB variable is provided. ATX statistics are divided
into six general groups:
