|Sorry I've been away so long. I've been sicker'n a dog for 4 days now. I believe I'm over the worst but I still feel like death warmed over.|
I'm sorry I can't be of more help but this is much more of a "hand-on" situation for me since your VLAN and cisco skills are lacking. If I had the equipment here, I could build the config for each piece and test. But I can't. Here's what I would do if this were me.
First, I'd get all the cisco equipment together into one room and I would lab this out one step at a time. Starting with zero'ing the config on all cisco devices. Once I had them all back to factory defaults I would start by configuring one switch at a time.
Give them an IP on the management VLAN (ie: VLAN 1)
switch 1: 192.168.1.1 SM 255.255.255.0
switch 2: 192.168.1.2 SM: 255.255.255.0
switch 3: 19126.96.36.199 SM: 255.255.255.0
Then configure uplink ports. On switch 1, set port 24 (48 if a 48 port switch) as a "trunk" port. On switch 2, set port 24 as a trunk port. Now connect the two with a crossover cable. Plug a client PC into any port on switch 1, and another on switch 2 and give them IP's in the same subnet as the switche (ex: 192.168.1.100, 101).
You should be able to ping one client from the other and vice versa. You should also be able to ping both switches from both clients as all are on the same subnet and plugged into VLAN 1 ports.
If this doesn't work, you're screwed and need some help from someone who can come to your house and give you a hand at the console.
If it does work, configure port 23 on switch 2 as an uplink (trunk) port to port 24 on switch 3. Now repeat the test procedure above and confirm all is working as it should.
At this point you should have the following:
IP: 192.168.1.1 SM: 255.255.255.0
VLAN 1 on all ports
Port 24 "trunk" port to switch 2
IP: 192.168.1.2 SM: 255.255.255.0
VLAN 1 on all ports
Port 24 "trunk" to port 24 on switch 1
Port 23 "trunk" to port 24 on switch 3
IP: 192.168.1.3 SM: 255.255.255.0
VLAN 1 on all ports
Port 24 "trunk" to port 23 on switch 2
Now you add a second VLAN. We'll call it VLAN 2 and lets make it your data (internet) VLAN. Once you've created VLAN 2 on all 3 switches assign it to some ports on each switch. Just for simplicity's sake, make ports 2-8 VLAN 2 (I always keep port 1 on every switch as VLAN 1 - a management port, so I can plug a laptop in to it in case I need to to troubleshoot an issue). Ensure you've removed VLAN 1 from ports 2-8 and ensure the primary VLAN ID for ports 2-8 is 2. Also, ensure you've added port 2 to your trunk ports. They should now show the following:
Primary VLAN ID (Base VLAN/baseband) = 1
Allowed VLANs = 1,2
Now plug your internet SOHO router into any VLAN 2 port and a DHCP enabled client into any other VLAN 2 port. Client should get TCP/IP settings from SOHO Router and have internet access. If this doesn't work, again, you've done something wrong and need help.
If it works, continue on to adding VLAN 3....same theory as adding VLAN 2. However, this is the VLAN you want segregated but to still have internet access so you'll have to have the 2800 connected to your network with an interface plugged into a VLAN 3 port on a switch and another to a VLAN 2 port. You will want to do this one interface at a time. Configure routing between the two so VLAN 3 has internet access through VLAN 2.
That's about all I can tell you. Again, it's been about ten years since I had to work with Cisco so I don't remember all the CLI commands offhand and have no interest in digging out a cisco switch to refresh my memory.
If you can't get it working after all this, I recommend you hit a cisco forum and ask for help there from someone who works with cisco every day.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
