In this post I list the commands to create VLAN 2, name it to dmz and place a range of ports in the VLAN. Finally I use a show command to look at the VLAN configuration.
switch1#conf t
switch1(config)#vlan 2
switch1(config-vlan)#name dmz
switch1(config-vlan)#end
switch1#conf t
switch1(config)#interface range FastEthernet 0/17 - 24
switch1(config-if-range)#switchport access vlan 2
switch1(config-if-range)#end
switch1#sh vlan brief
