Usage guidelines
When a MAC address frequently moves 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 to be one record.
An IRF member device can generate a maximum of 200 MAC address move records.
Examples
# Display the MAC address move records for a slot.
<Sysname> display mac-address mac-move slot 1
