Chapter 5 Advanced Configuration •• Port Displays the RMON statistics for the selected port. •• LAG Displays the RMON statistics for the selected LAG. 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 the 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. 8-Port 10/100/1000 Gigabit Switch with Webview Owner Displays the device or user that defined the alarm. The Add to List button adds the RMON Alarms Table entry. The Alarm Table area contains the following additional field: Counter Value Displays the current counter value for the particular alarm. Statistics > RMON Events An RMON Event determines the action to take when an alarm is triggered. The response to an alarm can include logging the alarm or sending an SNMP trap message. If the response corresponding to an alarm has not yet been defined, use the RMON Event screen to configure the Event Setting table. Statistics > RMON Events Add Event Event Entry Displays the event. Community Displays the community to which the event belongs. Description Displays the user-defined event description. Type Describes the event type. Possible values are: •• None Indicates that no event occurred. •• Log Indicates that the event is a log entry. •• Trap Indicates that the event is a trap. •• Log and Trap Indicates that the event is both a log entry and a trap. Owner Displays the device or user that defined the event. 28
