How to configure different VLANs to communicate with each other on a three-tier exchange

This experiment needs:

By planning VLAN 100 and VLAN 200 in Cisco Catalyst 3550来, and configuring DHCP to have the VLAN100 personnel computer obtain an IP address for 192.168.0.0/ 24, let VLAN200 market computer to obtain IP address for 172.16.0.0/24. Because the marketing department and the Ministry of Personnel because of business relationship, need two servers to communicate with each other, where also need to configure the VLAN in 3550 to communicate with each other.

Experiment topology:

The first step of the experimental process is to configure the Catalyst 3550 Base configuration

Switch> Switch>enable Switch#conf T Enter configuration commands, one per line. End With cntl/z. Switch (config) #host 3550 3550 (config) #no IP do lo 3550 (config) #line con 0 3550 (config-line) #no exec-t 3550 (config-line) #logg syn 3550 (Config-line) #exit

The second step is to divide the VLAN 100 and VLAN 200 in Catalyst 3550

Enter the global configuration mode and divide the VLAN (Do Catalyst 3500 support the VLAN in global mode?) ) 3550 (config) #vlan 100 Give VLAN100 a name. 3550 (Config-vlan) #name Renshibo 3550 (Config-vlan) #int F0/13 3550 (config-if) #switchport mode access 3550 (config-if) #switchport Access VLAN 100 3550 (config-if) #spanning-tree portfast When do I need to configure portfast under the switch interface? Is it OK if you don't configure it here? %warning:portfast should only is enabled on ports connected to a single Host. Connecting hubs, concentrators, switches, bridges, etc ... To this interface when Portfast is enabled, can cause temporary bridging loops. Use with CAUTION %portfast has been configured on FASTETHERNET0/13 but'll only Have effect when the interface was in a non-trunking mode. 3550 (config-if) #vlan 200 3550 (Config-vlan) #name Shichangbo 3550 (Config-vlan) #int F0/15 3550 (config-if) #sw MO acc 3550 (config-if) #sw ACC VLAN 200 3550 (config-if) #spanning-tree portfast %warning:portfast should only is enabled on ports connected to a single Host. Connecting hubs, concentrators, switches, bridges, etc ... To this interface when Portfast is enabled, can cause temporary bridging loops. Use with CAUTION %portfast has been configured on FASTETHERNET0/15 but'll only Have effect when the interface was in a non-trunking mode.
