Alarm Configuration

Viewing Alarm Status

The Basic Alarm Configuration window contains all the fields you need to configure one or more of the three basic alarms available for each interface installed in your RMON device:

Kilobits — Total Errors — Broadcasts/Multicasts

Use these fields at the top of the window to change the alarm type whose status is displayed in the list box. For example, if the Kilobits option is selected, the information in the list box pertains to the status of the Kilobits alarm type for each installed interface. Before you configure an alarm or alarms, be sure the appropriate option is selected here.

The available alarm variables are:

•Kilobits (ifInOctets) — tracks the number of octets of data received by the selected 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 thresholds accordingly. For example, to set a rising threshold of 1250 octets, enter a threshold value of 10; to set a falling threshold of 625 octets, enter a threshold value of 5.

•Total Errors (ifInErrors) — tracks the number of error packets received by the selected interface.

•Broadcast/Multicast (ifInNUcast) — tracks the number of non-unicast — that is, broadcast or multicast — packets received by the selected interface.

Note that the three pre-selected alarm variables are all MIB II variables; this allows you to

TIP configure alarms for any installed interface — even those for which no specific RMON statistics yet exist.

Port Number

Provides a sequential indexing of the interfaces installed in your RMON device.

IF Number

Displays the interface number assigned to each available interface. Note that because of the mismatch between physical interfaces on the device and the sequential port numbers assigned to the INB and the Ethernet/Fast Ethernet interfaces, the INB interface is indexed 5 and the Ethernet/Fast Ethernet interfaces are indexed 6 through 17.

IF Type

Displays each interface’s type: Ethernet or Other (for the INB interface). Note that there is no type distinction between standard Ethernet and Fast Ethernet.
