Well, what I was trying to ask was: Doesn't Vlan1 already have an Ip Address associated with it (meaning that I wouldn't need to put one on it anyways)? Vlan10, on the other hand, I Do need to put one on, which makes sense, but it's Vlan1 that I'm not understanding. Either way, I guess I...

I was also told that I don't need to put an ip helper-address command on Vlan1; only on Vlan10. So by adding an IP Address to a Vlan am I essentially turning it into an SVI (Switch Virtual Interface)? This is what Cisco says about it: " VLANs divide broadcast domains in a LAN environment...

Hmm. So I have to put a IP Address on Vlan1? I thought Vlan1's Network ID was the Switch itself's?

Basically what I'm going to do is steal a port from Vlan1 and make it a part of Vlan10. Every other port should stay in Vlan1.

But isn't Vlan1 already created by default (The Management Vlan)?

Yeah, I'm just wanting to add a Vlan10 to the switch which will be assigned to 1 port (for now atleast). That's what you're saying I should do, right?

What are the steps to turn a L2 Cisco 3560 into a L3? I also want to add a Vlan10 (w/ just one port) to the switch, as well. I also have an external DHCP server configured for Vlan1 (which is currently working) & Vlan10 (wasn't working before I reset switch), and I want it setup to function...

Is a Layer 3 Router necessary in a network that has a Layer 3 Switch? I ask this question because I am setting up a network configuration that currently has includes a: Layer 3 Kentrox Router Layer 3 3560 Nuvox Box 2 PC's (PC #1 = VLAN1 & PC #2 = VLAN10) They are setup like this: PC 1&2 -->...

Thanks viper for the help. Just so you know, the Kentrox isn't the one routing between the vlans, or atleast it shouldn't be. The 3560 should actually doing the inter-vlan routing. Is an SVI basically a vlan?

See I'm using a L3 3560 switch, so that's probably why I was able to get it to work by changing the GW's to the 3560 for devices on VLAN1, but if you are wanting to use a L3 Router to route between VLANs vs. a L3 interface on a L3 switch then, yes, you need to point the GW's to the L3 Router (as...

What I meant is you may need to change the GW for devices on VLAN1 to the Switch itself and not the Router. That's what I did in my situation and I could get inter-vlan routing going between the VLANs. Of course, I couldn't and still can't get devices on VLAN10 to the internet.

You may need to change the GW on VLAN1 to the 4506 if you haven't already done so. That may get you the ability to ping VLAN10 from VLAN1. Just a thought.....

anybody? viper? any suggestions?...please...

Question: If I configure a L3 interface on the 3560 (no switchport cmd, IP address command, etc.), does it have to left unused w/ nothing plugged into it or can I still use it as a L2 port like the rest of the ports? Also, once I give the L3 interface an IP address does VLAN1's GW change to...

Here's my layout: My PC --> 3560 --> Kentrox Router/Firewall --> Nuvox Box An externtal DHCP Server is also connected to 3560. What I want to happen: VLAN1 & VLAN10 can communicate My PC (VLAN1) --> 3560 --> Other PC (VLAN10) & vice versa DHCP addresses get to VLAN10 from the external...

Yeah, our default static route is to our Kentrox L3 Router/Firewall (which we are only wanting to use if devices need to get to the internet; any other L3 traffic we want the 3560 to route) which is then connected to our Nuvox Box that gets us to the internet. So you are saying that the GW for...

Thanks viper. I will see if this helps.

I am trying to add an extra VLAN (VLAN10, .10 subnet) to my 3560 and to get devices on the VLAN to acquire network information via an external DHCP Server and to also be able to the internet like devices on VLAN1. Here is my problem with my current configuration: 1) DHCP on VLAN10 does not...
