switchport port-security maximum
This command does not require a license.
Maximums for Access Ports and Trunk Ports
For an interface used as an access port, we recommend that you use the default interface maximum of one
secure MAC address.
For an interface used as a trunk port, set the interface maximum to a number that reflects the actual number
of hosts that could use the interface.
Interface Maximums, VLAN Maximums, and the Device Maximum
The sum of all VLAN maximums that you configure on an interface cannot exceed the interface maximum.
For example, if you configure a trunk-port interface with an interface maximum of 10 secure MAC addresses
and a VLAN maximum of 5 secure MAC addresses for VLAN 1, the largest maximum number of secure
MAC addresses that you can configure for VLAN 2 is also 5. If you tried to configure a maximum of 6 secure
MAC addresses for VLAN 2, the device would not accept the command.
Examples
This example shows how to configure an interface maximum of 10 secure MAC addresses on the Ethernet
2/1 interface:
switch# configure terminal
switch(config)# interface ethernet 2/1
switch(config-if)# switchport port-security maximum 10
switch(config-if)#
