Routing a 3550

I have a 3550 24 FX that I am trying to set up routing on. I have the following networks ( thru I have given each port an ip in that subnet, created a 6 seperate VLANs, and enabled routing globally as well as on each VLAN. How ever I cannot ping from my PC to a different network, but I can ping other networks on the 3550's ping tool.

I am a first timer with setting something like this up. Could anyone please give me some step by step instructions on how to make this work using the GUI? Also, I should with routing set up be able to ping across networks from my computer, correct?


Re: Routing a 3550

Hi Danburger,

yes after enabling routing on 3550 2 computers in different subnet should be able to talk to each but few things to remember.

1) Make sure you enable "ip routing" on global config mode

2) If you hace created logiocal interfaces like "interface vlan 2" and so on no need to assign ip address on ports.

3) Just follow simple steps via CLI and it will work

3550(config)#ip routing

3550(config)#int vlan 1


3550(config)#int vlan 2


3550(config)#int vlan 3





3550(config)#int vlan 6


Once you are done with that just assign few machines on port and put them to the specific vlan


3550(config)#int fa0/1

3550(config-if)#swithport mode access

3550(config-if)#switchport access vlan 2

3550(config)#int fa0/2

3550(config-if)#switchport mode access

3550(config-if)#switchport access vlan 3

and so on

and once you are done attach a machine on these 2 ports and just assign them respective subnet address and same ip as gateway which you have assigned on their logical interfaces and you will see that they will start talking to each other

Remember if you create logical interfaces no need to put ip address on physical interfaces because your logical interfaces will take caree of ip address and routing.

Machines must be connected to the physical ports with respective vlans assigned on the ports.
