To configure vlans on the switches and router do the following:

connect to the Core Router

UNIX> telnet core0

Trying x.x.x.x...
Connected to core0.
Escape character is '^]'.

Cisco has tab completion. The shell will recognize the command as long as you have typed enough for it to be distinct. Use '?' for help with specific commands. The following shows the current configuration

core0# sh ru           

look for availiable vlan or next one to use. <Enter> to scroll down <SpaceBar> for page at a time. Any other key will exit the pager.)

(use the configs above as a reference when entering the new one)
(much of the config can be simply copied and pasted)

core0# config t  (configure terminal)
Enter configuration commands, one per line.  End with CNTL/Z.
core0(config)#int fa0/0.<new vlan #> (in this case 233 is the next availiable)
core0(config-subif)#interface FastEthernet0/0.<new vlan #> (in this case 233)
core0(config-subif)#description <client description>
core0(config-subif)#encapsulation dot1Q <new vlan #> (in this case 233)

(for the vlan config you have to use 1+<actual network address>)

core0(config-subif)#ip address <network address+1> <netmask>
(ie: if actual network address is 209.144.224.224 use 209.144.224.225 here)
