Surely there are a lot of solutions; which I'd do is:
Define a different VLAN for each floor.
Connect the catalysts in each floor with trunk interfaces (802.1q)
Connect a Fast or Giga ethernet interface from a router to one of the
switches. You must setup that interface (both on the router an on the
switch side) as
DOT1Q. On the router you can do it with the following config:
-- Note: VLAN 101 - Floor 1
VLAN 102 - Floor 2
VLAN 103 - Floor 3
interface fastethernet 0/0 (for example)
full-duplex (Duplex full?)
speed 100
no ip address
interface fastethernet 0/0.101
encap dot1q 101
ip address 10.100.1.254 255.255.255.0
interface fastethernet 0/0.102
encap dot1q 102
ip address 10.100.2.254 255.255.255.0
interface fastethernet 0/0.103
encap dot1q 103
ip address 10.100.3.254 255.255.255.0
If you tell us which switches are you using (cat or IOS based) I can put
you a config for that; assuming they are IOS, it is more or less:
--- Switch on floor 1:
interface FastEthernet0/1
switchport access vlan 101
switchport mode access
duplex full
speed 100
interface FastEthernet0/2
switchport access vlan 101
switchport mode access
duplex full
speed 100
.......
! Trunk to floor 2
interface FastEthernet0/10
switchport mode trunk
duplex full
speed 100
..............
Switch on floor 2:
interface FastEthernet0/1
switchport access vlan 102
switchport mode access
duplex full
speed 100
interface FastEthernet0/2
switchport access vlan 102
switchport mode access
duplex full
speed 100
.......
! Trunk to floor 1
interface FastEthernet0/10
switchport mode trunk
duplex full
speed 100
! Trunk to floor 3
interface FastEthernet0/11
switchport mode trunk
duplex full
speed 100

Asunto: Subnet question [7:60711]
This might be a very elementary question for some of you guys but I would
appreciate the answer.
If an office which has 3 different floors and has Cisco routers and
catalyst
switches and windows environment. We need to configure it in such a way
that
each floor is on its own subnet for example
floor1 100.10.1.0
floor2 100.10.2.0
floor3 100.10.3.0
Also if a computer which has IP address in subnet 100.10.1.0 is moved from
floor 1 to floor 2, it should not communicate with the network unless its
IP
address is changed to one in 100.10.2.0 subnet.
How it can be accomplished?
Thank you
Nitin
