Enabling MAC address synchronization

(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.
(In IRF 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.
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.

When Client A roams to AP D, Device B learns a MAC address entry for Client A. Device B
advertises it to Device A to ensure service continuity for Client A, as shown in
