By default, the maximum number of
MAC addresses that can be
learned on an interface is not
configured.
Configuring the device to forward unknown frames
after the MAC learning limit on an interface is
reached
In this document, unknown frames refer to frames whose source MAC addresses are not in the MAC
address table.
You can enable or disable forwarding of unknown frames after the MAC learning limit is reached.

IMPORTANT:
To make this feature take effect in an IRF fabric, you must also enable MAC address synchronization by
using the mac-address mac-roaming enable command.
