Parameters
interval interval: Specifies the interval for detecting MAC address moves, in the range of 1 to
60 minutes. If you do not specify this option, the default setting of 1 minute is used.
Usage guidelines
With MAC address move notifications enabled, the system records the MAC address move logs
every MAC move detection interval. Each record of the MAC address move logs contains the
following information:
• MAC address.
• VLAN ID of the MAC address entry.
• Current port and source port of the MAC address moves.
• Number of MAC address moves within a detection interval.
A MAC address can have only one MAC address move record. If a MAC address moves multiple
times, the new record overrides the old record.
