Just trying to learn some routing with a 3800 switch

[dTardis]

So I am NOT a network engineer, but I sometimes play one at work. We are exploring adding VLANS to breakup our broadcast domain and to add VOIP traffic. To that end we will need to route traffic between VLANs. I am trying to figure out exactly how to get a 3800 switch to do this. So please be gentle with me. Here is what I have so far.

When I add a computer to the 172.16.201.0/24 network it can ping 172.16.201.1 AND 10.2.3.50, but that’s it. I just don't know where to go from here.

In VLAN201 and 202 you untagged 1 port, if you want to be able to ping other devices you coud set port 3 untagged in VLAN 201

Put a PC on that port with ip addres 172.16.201.10 and you should be able to ping that

If you want to distribute the VLAN's to other switches through a single uplink you should start tagging ports with VLAN201 and 202

Thanks for the reply.

Sorry if I was not clear enough.

My primary network is on VLAN 1. I have PC's on that network 10.2.x.x - I connect port 20 to another switch on my network.

I connect a PC to Port 1. I give it an IP of 172.16.201.10

From that PC I can ping 172.16.201.1 (the switch on vlan 201), I can also ping 10.2.3.50 (the switch on vlan 1). I can not ping any of the other PC's on my network. For example 10.2.0.2

I hope that makes it a little more clear.

[dTardis]

Any other ideas?

dTardis,

What is the default gateway set to on the PCs that you are trying to ping? If you can ping the switch but not the PCs you either have an incorrect gateway set or the PCs firewall is blocking you. As far as the switch is concerned routing is working as expected.
