Address

MAC address learning reduces outgoing broadcast traffic. For MAC address

Learning

learning to occur on a port, the port itself must be active with address learning

 

enabled.

 

 

Limited Number

Use this field to limit the number of (dynamic) MAC addresses that may be learned

of Learned

on a port. For example, if you set this field to "5" on port 2, then only the devices with

MAC Address

these five learned MAC addresses may access port 2 at any one time. A sixth device

 

would have to wait until one of the five learned MAC addresses aged out. MAC

 

address aging out time can be set in the Switch Setup screen. The valid range is

 

from 0 to 16K. “0” means this feature is disabled, so the switch will learn MAC

 

addresses up to the global limit of 16K.
