Enabling MAC address software learning on an
interface
The MAC address software learning feature applies to a Software Defined Network (SDN).
On an SDN network, the device uploads the learned MAC addresses to the controller, and the controller
issues the received MAC address to other remote devices, which reduces unnecessary broadcasts.
An interface can learn MAC addresses through one of the following methods:
Hardware learning—MAC addresses are learned through hardware (the default setting).
•
Hardware learning requires the software to periodically check whether the hardware has learned
new MAC addresses, and then uploads the learned MAC addresses to the controller.
Software learning—The software learns MAC addresses, issues the learned MAC addresses to the
•
hardware, and uploads the MAC addresses to the controller. Software learning has a faster
learning speed than hardware learning because software learning does not require a periodical
check.
To avoid impacting the system, HP recommends not enabling this feature when a large number of MAC
addresses change frequently.
To enable MAC address software learning on an interface:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface or Layer 2
aggregate interface view.
3. Enable MAC address
software learning on the
interface.
