Basic Cisco Switch Configuration - 2. Create and Modify VLAN
What is VLAN..? How Create VLAN..?
👇👇Please Find Below.. 👇👇
VLANs allow you to logically segment a LAN into different broadcast domains. In scenarios where sensitive data may be broadcast on a network, VLANs can be created to enhance security by designating a broadcast to a specific VLAN. Only users that belong to a VLAN are able to access and manipulate the data on that VLAN. VLANs can also be used to enhance performance by reducing the need to send broadcasts and multicasts to unnecessary destinations.

Below is the steps to be followed
- Crate a Packet Tracer Topology Lab
- Log into the switch using console or SSH (👈 Click on here to see how enable SSH access on switch )
- Configure Initial Setup on switch
- Create VLAN ID and give proper name
- Assign Ports/Multiple Ports to VLAN
- Modify VLAN (Rename, Delete, Change assigned Ports, Etc..)

Assign Ports/Multiple Ports to VLANThe port modes are defined as follows:
- Access Port - The frames received on the interface are assumed to not have a VLAN tag and are assigned to the specified VLAN. Access ports are used primarily for hosts and can only carry traffic for a single VLAN.
- Trunk Port - The frames received on the interface are assumed to have VLAN tags. Trunk ports are for links between switches or other network devices and are capable of carrying traffic for multiple VLANs.
To assign switch ports to VLANs we can follow below commands.Floor-1(config)#
Select single interface need to effect config
Floor-1(config)#interface fastEthernet 0/1 -- Option 1
Floor-1(config-if)#
Select multiple interface range need to effect config
Floor-1(config)#interface range fastEthernet 0/1-10 -- Option 2
Floor-1(config-if-range)#
Change port mode to access
Floor-1(config-if)#switchport mode access
Assign port to VLAN
Floor-1(config-if)#switchport access vlan 10
Floor-1(config-if)#
Make port status UP (Enable)
Floor-1(config-if)#no shutdown
Moving back to global config mode
Floor-1(config-if)#exit
Floor-1(config)#

Modify VLAN (Rename, Delete, Change assigned Ports, Etc..)
For Rename any VLAN we just need to follow same config that followed to give name to VLAN.Floor-1(config)#
Initiate VLAN IDFloor-1(config)#VLAN 10
Giving name to to VLANFloor-1(config-vlan)#Name HR
For Delete VLAN we can follow below command.Floor-1(config)#no vlan <ID>Floor-1(config)#no vlan 10For Remover ports from VLAN we can follow below commands.Select single interface need to effect config
Floor-1(config)#interface fastEthernet 0/1 -- Option 1
Floor-1(config-if)#
Floor-1(config-if)#no switchport access vlan
Select multiple interface range need to effect config
Floor-1(config)#interface range fastEthernet 0/1-10 -- Option 2
Floor-1(config-if-range)#
Floor-1(config-if-range)#no switchport access vlan
