Usage guidelines
On an IRF fabric, if ports on different IRF member devices are Selected ports from the same
aggregation group, MAC address entries are synchronized among these IRF member devices. They
are synchronized whether or not MAC address synchronization is enabled for the IRF fabric. For
more information about aggregation groups, see Layer 2—LAN Switching Configuration Guide.
The MAC address table size might vary by IRF member device. With MAC address synchronization
enabled, MAC address entries exceeding the table size of an IRF member device cannot be
synchronized to the MAC address table.
