Objective: Implementation and Operations
SubObjective: Configure a switch with VLANs and inter-switch communication

Multiple Answer Multiple Choice

Which steps are required to add a VLAN? (Choose two.)

A. Create the VLAN.
B. Assign a subnet to the VLAN
C. Define the encapsulation type.
D. Add the VLAN to the STP domain.
E. Enable an appropriate routing protocol.
F. Add the desired switch ports to the VLAN.

Answer:
A. Create the VLAN.
F. Add the desired switch ports to the VLAN.

Tutorial:
To add a VLAN, you must first create the VLAN and then assign the desired ports to the VLAN.

For example, suppose you want to add VLAN 2 to Switch 1 and add Ethernet ports 0/3 and 0/4 to the new VLAN. You would use the following commands to accomplish this task:

Switch1(config)# vlan 2
Switch1(config-vlan)# end
Switch1(config)# interface e 0/3
Switch1(config-if)# switchport access vlan 2
Switch1(config-if)# interface e 0/4
Switch1(config-if)# switchport access vlan 2

The vlan 2 command creates VLAN number 2. Assigning a VLAN number is required, but assigning a VLAN name is optional. If a name is not specified, the VLAN number will be appended to the word “VLAN” to create a default name for the VLAN. The VLAN created in the configuration above would be named VLAN0002 because the VLAN name was not specified with the vlan command.

The interface e 0/3 command switches to interface configuration mode for Ethernet port 0/3. Assuming that the port has been configured as an access port, the switchport access vlan 2 command assigns Ethernet 0/3 to VLAN 2. The next command switches to interface configuration mode for Ethernet port 0/4, where Ethernet port 0/4 is added to VLAN2 using the switchport access vlan 2 command. The Catalyst switches also support dynamic VLAN-membership assignment using a VLAN Management Policy Server (VMPS). To configure ports for dynamic assignment use the switchport access vlan dynamic command.
