Configuring SNMP Services
1-9
Memory Considerations
Polling statistics to determine whether they have reached a threshold and
reporting events when variables exceed thresholds requires router processing
capacity. When you set more thresholds and use shorter polling intervals, the
performance of the router will probably decline.
Traps
Using the SNMP trap parameters, you can configure which event log messages
the agent sends to the network management station as traps. You select the traps
the agent sends based on slot, protocol entity, and severity level. You can also
specify up to 50 exceptions, traps that the agent always sends, or never sends,
regardless of slot and regardless of how you configure the trap parameters. Refer
to “Editing Trap Parameters” later in this chapter for information on how to
specify which traps the agent sends.
RMON
When you enable a DCM, you automatically set up RMON Statistics and History
configurations; you can also choose to set up Matrix and Host configurations. Use
Site Manager to enable a DCM (refer to Connecting AN and ANH Systems to a
Network for details). To set up other RMON configurations and to view RMON
statistics, use Optivity
®
LAN or a third-party RMON network management
application.
You can use the Technician Interface to modify DCM or RMON parameters by
issuing
set and commit commands with the MIB object ID. This process is
equivalent to modifying parameters using Site Manager. For more information
about using the Technician Interface to access the MIB, refer to Using Technician
Interface Software.
Caution: The Technician Interface does not verify that the value you enter for
a parameter is valid. Entering an invalid value can corrupt your
configuration.
In addition, be sure to avoid running scripts that continually issue Technician
Interface commands while you are running another RMON network
management application. This combination can cause the SNMP agent to fill
the system buffers with RMON data, leading to a system restart.
