The second adding device, for current application being identified when the first adding device, after the source port number of message adds in new application identities exchange end oral thermometer as new application identities exchange end oral thermometer list item information, according to current application, be identified at and in application identities allocation list, search corresponding intelligent electronic device title, intelligent electronic device port title, and current application is identified, the current intelligent electronic device title finding, the current intelligent electronic device port title finding, message source port adds intelligent electronic device port table to as new intelligent electronic device port table list item information,
The second updating block, for upgrading with the source port number of message when the first updating block after the switch ports themselves number of the corresponding current application sign of application identities exchange end oral thermometer, with the source port number of message, upgrade the switch ports themselves number that in smart electronics port table, corresponding current application identifies;
Refresh unit, for when the result of determination of the first judging unit is when being, or when the second adding device is when current application sign, the current intelligent electronic device title finding, the current intelligent electronic device port title finding, message source port add intelligent electronic device port table to as new intelligent electronic device port table list item information, or when the second updating block uses the source port number of message to upgrade the switch ports themselves of corresponding current application sign in smart electronics port table, refresh application identities exchange end oral thermometer and intelligent electronic device port table.
10. switch according to claim 9, to intelligent electronic device port automatic learning system, characterized by further comprising step:
Also comprise the first delete cells, for detection of to switch and intelligent electronic device port be connected the information disconnecting time, the list item information corresponding with this intelligent electronic device port in deletion intelligent electronic device port table;
Or
Also comprise the second delete cells, for detection of the list item information in intelligent electronic device port table, if more than one list item information in Preset Time in intelligent electronic device port table is not refreshed, delete list item information corresponding in intelligent electronic device port table.
