System information

152 The Statistics Menu
This value ensures that the trigger will not be activated during a slow period of
network activity when a particular device or station is broadcasting.
• “Averaging period (sec)” spinbox—the amount of time in seconds that data will
be collected and averaged before a value is considered for the trigger. Sampling
is every second. Values for the averaging period can be from 1 to 100 (seconds).
• “Use current filter profile” checkbox—when selected, allows you to use the
current protocol filter.
Duplicate IP Addresses
This trigger activates when two IP addresses that are identical, from different
hardware devices, are seen on your network.
• “Use current filter profile” checkbox—when selected, allows you to use the
current protocol filter.
Ethernet Frame Errors
This trigger activates when a percentage of Ethernet frame errors are observed.
• “Percentage of frames with errors (0.01%)” spinbox—allows you to set the
percentage of frames, within the limits of the number of packets collected and the
averaging period, that will set off the trigger.
• “Minimum number of packets (trigger level)” textbox—allows you to set the
minimum number of packets collected before considering the data as a trigger
condition. This is set to ensure that a low network activity state does not trigger
an error alarm that is statistically meaningless.
• “Averaging period (sec)” spinbox—allows you to set the amount of time in
seconds that data will be collected and averaged before a value is considered for
the trigger. Sampling is every second. Values can be from 1 to 100 (seconds).
• “Use current filter profile” checkbox—when selected, allows you to use the
current protocol filter.
