Aim:
To
construct a VLAN and make the PC’s communicate among a VLAN
Requirements
Windows
pc – 6 Nos
CISCO
Packet Tracer Software (Student Version)
8
port switch – 1 No
Cat-5
LAN cable
Procedure
Open
the CISCO Packet tracer software
Drag
and drop 6 pcs using End Device Icons on the left corner
Select
8 port switch from switch icon list in the left bottom corner
Make
the connections using Straight through Ethernet cables
Give
IP address of the PCs as per table, ping between PCs and observe the transfer
of data packets in real and simulation mode.
Theory
A VLAN is a group of
devices on one or more LANs that are configured to communicate as if they were
attached to the same wire, when in fact they are located on a number of
different LAN segments. Because VLANs are based on logical instead of physical connections,
they are extremely flexible.
VLANs define broadcast
domains in a Layer 2 network. A broadcast domain is the set of all devices that
will receive broadcast frames originating from any device within the set. Broadcast
domains are typically bounded by routers because routers do not forward
broadcast frames. Layer 2 switches create broadcast domains based on the
configuration of the switch. Switches are multiport bridges that allow you to
create multiple broadcast domains. Each broadcast domain is like a distinct
virtual bridge within a switch.
