I am looking to configure separate Vlans on a single 3550 Cisco switch and have them communicate with each other. So far I have created the Vlans and Vlan interfaces. Now just looking to get them to talk to each other. I think they are configured correctly.

looking for a little help from my friends

Thanks

You need to assign IP's to the VLANs and enable IP routing on the 3550.  After that, they should route, no problems.

To do this enter the global configuration mode, and type "interface vlan x" where x is the number of the vlan.

Then configure the ip address as you would any other layer 3 device, I also like to add a description as it helps later.

As pseudocyber says if routing is enabled the traffic will pass from one VLAN to the other with no problems. To restrict this traffic just configure an ACL as you would on any router.

Hope that helps.

I am very new to Layer 3 switch.  but i understand the concept of Vlan and Layer 2,
is there any URLs where I can read more about Layer3 switches and some of configurations samples.
I had visited cisco website to read about swtiches like 3550, but it does not give much of configuration, only onto what the switch can do it's commands only.

please advise

Fox - if you want to read about how to Configure, Cisco's got a ton of that but you have to dig into the IOS manuals, not the marketing stuff.  Nortel's got some good stuff, but you can't get to it without a support contract.

Think of a Layer3 switch as a switch which can route.  You can do both on the same box.
