Parameters
slot slot-number: Specifies an IRF member device by its member ID. If you do not specify this option, the command displays MAC address move records on all member devices.
Usage guidelines
When MAC address moves for a MAC address always occur between the specified two interfaces, Layer 2 loops might occur in the network. To discover and locate loops, you can view the MAC address move records.
In the MAC address move records, records with the same MAC address, VLAN, source port, and current port are considered as to be one record.
An IRF member device can save a maximum of 20 MAC address move records. When the number of MAC address move records exceeds 20, the most recent record will override the oldest record based on the last MAC address move time.
Examples
# Display the MAC address move records on the IRF member device 2.
