Enabling Mac Address Synchronization - HP FlexFabric 12900 Series Configuration Manual

To configure the interface to forward unknown frames after the MAC learning limit is reached:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface view.
3. Configure the device to
forward unknown frames
received on the interface after
the MAC learning limit on the
interface is reached.

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.
