Usage Guide:
When configuring the max number of dynamic MAC address allowed by the port, if the number of
dynamically learnt MAC address on the port is already larger than the max number of dynamic MAC
address to be set, the extra dynamic MAC addresses will be deleted. This function is mutually
exclusive to functions such as dot1x, MAC binding, if the functions of dot1x, MAC binding or TRUNK
are enabled on the port, this function will not be allowed.
Examples:
Enable the number limitation function of dynamic MAC address in port 1/2 mode, the max number
to be set is 20
Switch(config)#interface ethernet 1/2
Switch(Config-If-Ethernet1/2)# switchport mac-address dynamic maximum 20
