Configuration Using the Web-based Utility

Oversize Packets  Displays the number of oversized packets (over 1518 octets) received on the interface since the device was last refreshed.

Fragments  Displays the number of fragments (packets with less than 64 octets, excluding framing bits, but including FCS octets) received on the interface since the device was last refreshed.

Jabbers  Displays the total number of received packets that were longer than 1518 octets. This number excludes frame bits, but includes FCS octets that had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a non-integral octet (Alignment Error) number. The field range to detect jabbers is between 20 ms and 150 ms.

Collisions  Displays the number of collisions received on the interface since the device was last refreshed.

Utilization  Displays the percentage of the interface utilized.

Statistics > RMON Alarms

The RMON Alarm screen is used to set network alarms. Network alarms occur when a network problem, or event, is detected. Rising and falling thresholds generate events.

Statistics > RMON Alarm

Add Alarm

Alarm Entry  Indicates a specific alarm.

Interface  Indicates the interface for which RMON statistics are displayed. To specify the interface, select Unit No. (default) and specify the unit number and port from the drop-down menus, or select LAG and select the LAG number from the drop-down menu.

Counter Name  Displays the selected MIB variable.

Sample Type  Defines the sampling method for the selected variable and comparing the value against the thresholds. The possible field values are:

•Absolute  Compares the values directly with the thresholds at the end of the sampling interval.

•Delta  Subtracts the last sampled value from the current value. The difference in the values is compared to the threshold.

Rising Threshold  Displays the rising counter value that triggers the rising threshold alarm. The rising threshold is presented on top of the graph bars. Each monitored variable is designated a color.

Rising Event  Displays the mechanism in which the alarms are reported. The possible field values are:

•LOG  Indicates there is not a saving mechanism for either the device or in the management system. If the device is not reset, the entry remains in the Log Table.

•TRAP  Indicates that an SNMP trap is generated, and sent via the Trap mechanism. The Trap can also be saved using the Trap mechanism.

•Both  Indicates that both the Log and Trap mechanism are used to report alarms.

Falling Threshold  Displays the falling counter value that triggers the falling threshold alarm. The falling threshold is graphically presented on top of the graph bars. Each monitored variable is designated a color.

Falling Event  Displays the mechanism in which the alarms are reported. The possible field values are:

•LOG  Indicates there is not a saving mechanism for either the device or in the management system. If the device is not reset, the entry remains in the Log Table.

•TRAP  Indicates that a SNMP trap is generated, and sent via the Trap mechanism. The Trap can also be saved using the Trap mechanism.

•Both  Indicates that both the Log and Trap mechanism are used to report alarms.

Startup Alarm  Displays the trigger that activates alarm generation. Rising is defined by crossing the threshold from a low-value threshold to a higher-value threshold.

Interval  Defines the alarm interval time in seconds. Owner  Displays the device or user that defined the alarm. Click Add to List to add an entry to the Alarm Table.

Alarm Table

The Alarm Table lists the alarms that have been defined using the Add Alarm section. The Alarm Table contains a colunn for each field in the Add Alarm section, plus the following column:

Counter Value  Displays the current counter value for the particular alarm.
