mac-learn
Configures the number of MAC addresses an interface can learn.
Syntax
mac-learn {limit learn-limit-value | no-limit}

● limit learn-limit-value — Enter a value from 1 to 3072.
● no-limit — The interface learns the maximum number of MAC addresses that the system
supports.
Default One MAC address
Command Mode
CONFIGURATION-PORT-SECURITY
Usage
Information
After you enable port security on an interface, by default, the interface learns a maximum of one MAC
address. Use the mac-learn limit command to configure the number of MAC addresses an interface
can learn.
If the system contains more static MAC addresses than the MAC address learn limit, the system displays
an error message. You can delete a few static MAC addresses or increase the number of MAC addresses
the port can learn.
If the total number of dynamic MAC addresses on an interface is greater than the newly configured MAC
learn limit, the dynamic MAC addresses are flushed.
Example
OS10(config-if-port-sec)# mac-learn limit 100
