Answer Posted / m hussain
virtual lan is nothing but dividing a big switch into many switch. suppose if we have 12 port switch . if we divide this switch into two switch . suppose vlan 1 and vlan 2 . suppose in each vlan we have 4 and 6 port is there respectively.after dividing the vlan thus the computer connected with vlan1 can't communicate with vlan2 computer . thus we get two switch from one switch . in a sw. we can create many vlan upto 1005 vlan.
