The interval history includes statistical information such as the number of MAC addresses that move over the specified period, the total number of MAC address moves, which MAC addresses have moved, and how many times a MAC address has moved.
There is an upper limit on the number of MAC addresses for which MAC address-specific data is collected. This limit is necessary because it is not possible to report on all MAC addresses when many move.
Avoid threshold rates and sampling intervals that are too small. If you choose a small threshold and a sampling interval that is also small, an unnecessary high number of traps could occur.
The no form of the command disables movement notifications and stops collecting statistics for the movement of MAC addresses.
The following example sets the notification interval to 300 seconds.
device(config)# mac-movement notification interval-history 300
The following example sets the notification for 500 moves and a sampling interval of 400 seconds.
device(config)# mac-movement notification threshold-rate 500 sampling-interval 400
