Enabling MAC address roaming
After you enable MAC address roaming on an IRF fabric, each member switch advertises learned MAC
addresses to other member switches.
As shown in Figure 6, D
evice A and Device B form an IRF fabric enabled with MAC address roaming.
They connect to AP C and AP D, respectively. When Client A associates with AP C, Device A learns the
MAC address of Client A and advertises it to the member switch Device B.
Figure 6 MAC address tables of devices when Client A associates with AP C
If Client A roams to AP D, Device B learns the MAC address of Client A and advertises it to Device A to
ensure service continuity for Client A, as shown in Figure 7.
