www.qtech.ru

“no switchport mac-address dynamic maximum” command is used to disable the

number limitation function of dynamic MAC address on the port.

 Parameters: <value> upper limit of the number of dynamic MAC address of the port,

ranging from 1 to 4096.

 Default Settings: The number limitation function of dynamic MAC address on the port

is disabled.

 Command Mode: Port mode.

 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 1/0/2 mode, the

max number to be set is 20
