command in cisco packet tracer

[nizamshaikh2504]

could anyone help me why we use the command "switchport mode access" in packet tracer ?

switch successfully create vlan without using this command also.

That command is not used to create the vlan. 

It is used to tell the port what mode to run in ie. is it an access port in just one vlan or is it a trunk port carrying traffic for multiple vlans.

Hi

As Jon mentioned, this command line is not used to create a VLAN, it is configured under a interface to represent it as access port:

interface g1/0/1

switchport

switchport mode access

switchport access vlan 100

no shutdown

This type of port is used to connect hosts only.
