Basic Alarm Configuration
Creating alarms; assigning events and actions; viewing an alarm log
Through the RMON Alarm and Event functionality supported by your 7C0x
SmartSwitch, you can configure some basic alarm thresholds for each available
bridge port interface; you can also define a response to each alarm condition.
About Basic Alarms
Using the Basic Alarm Configuration application, you can define both rising and
falling alarm thresholds for three selected MIB-II objects: ifInOctets, ifInNUcast,
and ifInErrors. Because these pre-selected objects are not RMON-specific, you can
configure alarms for all available bridge interfaces in your SmartSwitch chassis —
including those, like FDDI, for which no specific RMON statistics currently exist.
In addition to configuring separate rising and falling thresholds, you can also
configure your device’s response to an alarm condition: when a threshold is
crossed, the SmartSwitch can create a log of alarm events, send a trap notifying
your management workstation that an alarm condition has occurred, or both; you
can even configure an alarm to enable or disable bridging on the offending port in
response to a rising or falling alarm condition.
!
CAUTION
The current version of the Basic Alarm application can only be used on devices which are
configured to operate as traditional bridges, as it has some dependencies on bridge-specific
table information; if you try to launch the application against a device which is configured
for SecureFast switching, the window will paint, but the interface list box will remain
blank.
TIP
Current versions of the Basic Alarm Configuration application do not provide a means for
viewing any alarm logs you choose to create; if you wish to use the Log option, you can
view the associated log via the MIBTree or any similar SNMP-based tool. See Viewing an
Alarm Log, page 3-10, for details.
