addresses are used on the system, the MAC addresses of both stations and the ports they accessed are
logged.
If you enable both duplicated IP detection and duplicated IP trap, the designated trap receiver gets an alert

detection must be enabled.
By default, duplicated IP detection and trapping are enabled.

4.3.2 Enabling and Disabling Station Movement Trap
The station movement trap security measure ensures that when any end station is moved from one switch
port to another, an alert is sent to the designated trap receiver. Station movement is detected when a
station’s MAC address (already learned by the switch) appears on a different switch port. The station
movement trap includes the station’s MAC address and IP address (if available) and the switch’s port
numbers.
By default, station movement trap is disabled.
To enable or disable detection of the movement of a station on the switch:
1. From the Configuration Menu, type
t
to access the Security Management Menu.
2. Type
s
to toggle the station movement trap.
