Step 1.
|
Enter VLAN 1 configuration mode using the interface vlan 1 global configuration command (from any config mode).
|
|
Step 2.
|
Use the ip address dhcp command, instead of the ip address ip-address mask command, on the VLAN 1 interface.
|
|
Step 3.
|
Enable the VLAN 1 interface using the no shutdown interface subcommand
|
|
Step 4.
|
Do not configure the ip default-gateway global command

Port security configuration flow: |
|
Definition
-Make the port an access port, which means that the port is not doing any VLAN trunking.
-Enable port security and then configure the actual MAC addresses of the devices allowed to use that port |

The actual steps to configure port security on a switch
Up to 5 steps |
|
Definition
|
Step 1.
|
Make the switch interface an access interface using the switchport mode access interface subcommand.
|
|
Step 2.
|
Enable port security using the switchport port-security interface subcommand.
|
|
Step 3.
|
(Optional) Specify the maximum number of allowed MAC addresses associated with the interface using the switchport port-security maximum number interface subcommand. (Defaults to one MAC address.)
|
|
Step 4.
|
(Optional) Define the action to take when a frame is received from a MAC address other than the defined addresses using the switchport port-security violation {protect | restrict | shutdown} interface subcommand. (The default action is to shut down the port.)
|
|
Step 5A.
|
Specify the MAC address(es) allowed to send frames into this interface using the switchport port-security mac-address mac-address command. Use the command multiple times to define more than one MAC address.
|
|
Step 5B.
|
Alternatively, instead of Step 5A, use the “sticky learning” process to dynamically learn and configure the MAC addresses of currently connected hosts by configuring the switchport port-security mac-address sticky interface subcommand
