For the switch to act as a DHCP client?

Definition
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

For a statically configured IP, can check it by issuing the show run

How would an IP configured by DHCP be checked?

Definition
show dhcp lease

Important details for IP addresses when using the

show interface vlan 1 command

Definition

- lists the interface status of the VLAN 1 interface



- output mentions that the address is either statically configured or DHCP-leased.

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

Term

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

Switching

 

To define an action to take when a frame is received from a MAC address other than the defined addresses when configuring port security?


What is the default?

Definition

 switchport port-security violation {protect | restrict | shutdown}interface subcommand.

 

 

 (The default action is to shut down the port.)

Term

Switching

 

When configuring port security, which command specifies the MAC address(s) allowed to send frames into this interface?

Definition
