# Revision history [back]

The tap update interval is dictated by the value of TAP_UPDATE_DEFAULT_INTERVAL, currently defined in epan/prefs.h as 3000 (i.e., 3 seconds). If you want a different update interval, then currently you would have to modify that value and then recompile Wireshark yourself to make use of the new interval.

If you want to be able to dynamically change the tap interval, then you may wish to open a Wireshark bug report asking for this capability, and if it's feasible and someone is willing/able to make this change, then it might get implemented.
