Port Events Warning e-mail is sent when…
Link-ON The port is connected to another device.
Link-OFF
The port is disconnected (e.g., the cable is pulled out,
or the opposing device shuts down).
Traffic-Overload
The port’s traffic surpasses the Traffic-Threshold for
that port (provided this item is Enabled).
Traffic-Threshold (%)
Enter a nonzero number if the port’s Traffic-Overload
item is Enabled.
Traffic-Duration (sec.)
A Traffic-Overload warning is sent every
Traffic-Duration seconds if the average
Traffic-Threshold is surpassed during that time
period.
NOTE
The Traffic-Overload, Traffic-Threshold (%), and Traffic-Duration (sec) Port Event items
are related. If you Enable the Traffic-Overload event, then be sure to enter a nonzero
Traffic-Threshold percentage, as well as a Traffic-Duration between 1 and 300 seconds.

Using Line-Swap-Fast-Recovery
The Line-Swap Fast Recovery function, which is enabled by default, allows PT-7728 to return to
normal operation extremely quickly after devices are unplugged and then re-plugged into different
ports. The recovery time is on the order of a few milliseconds (compare this with standard
commercial switches for which the recovery time could be on the order of several minutes). To
disable the Line-Swap Fast Recovery function, or to re-enable the function after it has already
been disabled, access either the Console utility’s Line-Swap recovery page, or the Web Browser
interface’s Line-Swap fast recovery page, as shown below.
