Port 2/1 port security enabled with 00-90-2b-03-34-08 as the secure mac address
Trunking disabled for Port 2/1 due to Security Mode
Console> (enable)

Setting the Maximum Number of Secure MAC Addresses

You can set the number of MAC addresses to secure on a port. By default, at least one MAC address per
port can be secured. In addition to this default, a global resource of up to 1024 MAC addresses is
available to be shared by the ports. This means that if the entire global resource of 1024 MAC addresses
is used on some ports, you can still enable port security on the rest of the ports with a maximum of one
MAC per port.
If you reduce the maximum number of MAC addresses, the system clears the specified number of MAC
addresses and displays the list of removed addresses.
To set a number of MAC addresses to be secured for a particular port, perform this task in privileged
mode:
