Alarm Configuration4-4Basic Alarm ConfigurationWhen the window is first launched, no interfaces will be selected, and the, , and buttons will be grayed out: andwill activate when an interface is selected; will activate when aninterface which has experienced an alarm event is selected. The presence of anevent log is indicated by the double greater-than sign (>>) displayed to the left ofthe threshold value that was crossed.Viewing Alarm StatusThe Basic Alarm Configuration window contains all the fields you need toconfigure one or more of the three basic alarms available for each interfaceinstalled in your RMON device:Kilobits — Total Errors — Broadcasts/MulticastsUse these fields at the top of the window to change the alarm type whose status isdisplayed in the list box. For example, if the Kilobits option is selected, theinformation in the list box pertains to the status of the Kilobits alarm type for eachinstalled interface. Before you configure an alarm or alarms, be sure theappropriate option is selected here.The available alarm variables are:• Kilobits (ifInOctets) — tracks the number of octets of data received by theselected interface. Note that this value has been converted for you from octets(or bytes) to kilobits (or units of 125 bytes); be sure to enter your thresholdsaccordingly. For example, to set a rising threshold of 1250 octets, enter athreshold value of 10; to set a falling threshold of 625 octets, enter a thresholdvalue of 5.• Total Errors (ifInErrors) — tracks the number of error packets received by theselected interface.• Broadcast/Multicast (ifInNUcast) — tracks the number of non-unicast — thatis, broadcast or multicast — packets received by the selected interface.Port NumberProvides a sequential indexing of the interfaces installed in your RMON device.IF NumberDisplays the interface number assigned to each available interface. Interfacesinstalled in a SmartSwitch 7000 chassis are indexed according to an XXXXYYscheme, where X = the slot number in which the module containing the portresides, times 10,000; and Y = the physical index assigned to the port. Forexample, an interface number of 30002 would refer to port 2 on the moduleinstalled in slot 3 of the chassis.TIPNote that the three pre-selected alarm variables are all MIB II variables; this allows you toconfigure alarms for any installed interface — even those for which no specific RMONstatistics yet exist.
