Enabling MAC address synchronization

To avoid unnecessary floods and improve forwarding speed, make sure all cards have the same
MAC address table. After you enable MAC address synchronization, each card advertises learned
MAC address entries to other cards. (In standalone mode.)
To avoid unnecessary floods and improve forwarding speed, make sure all cards have the same
MAC address table. After you enable MAC address synchronization, each card advertises learned
MAC address entries to other cards of all member devices. (In IRF mode.)
As shown in
•
Device A and Device B form an IRF fabric enabled with MAC address synchronization.
•
Device A and Device B connect to AP C and AP D, respectively.
When Client A associates with AP C, Device A learns a MAC address entry for Client A and
advertises it to Device B.
