Gents,
I will try to describe what is being attempted and you guys tell me where I am wrong if you do not mind.
The layout is simple:
Top Layer
PowerConnect 7048 Server Switch 1
PowerConnect 7048 Server Switch 2 => These two are the server layer (top)
These are NOT stacked.
Five VLANs created on them as follows:
VLAN ID / Ports in use
100 - Port 1 to 14
101 - Port 15 to 30
102 - Port 31 to 38
103 - Port 39 to 46
1210 - Port 47 and 48
Middle Layer (Core)
PowerConnect 8132F Core Switch 1
PowerConnect 8132F Core Switch 2
These are connected to each other using ports 23/24. Idea is to create a LAG between the two. Something along these lines:
enable
configure
interface range tengigabitethernet 1/0/23-24
channel-group 1 mode active
The top two server switches are connected to the two cores through the 10GB Module on the back. One port on Server Switch 1 goes to Core Switch 1 port 1 and second port on Server Switch 1 goes to Core Switch 2 port 1. One port on Server Switch 2 goes to Core Switch 1 port 1 and second port on Server Switch 2 goes to Core Switch 2 port 1.
The idea is to have an active and a passive link to the core switches. This is one of the things I am not 100% sure on how to do it.
Do I just create a trunk between the server switches and the core ones? What is confusing to me is the active/passive thing. Someone threw together a diagram and this is what is says, an active/passive thing.
Bottom Layer
Here we have 7 x PowerConnect 7048s stacked. Anything that connects here is VLAN 101. Nothing else.
Three of the switches on the stack do have 10GB modules on the back so we have three connections going to Core Switch 1 and three going to Core Switch 2. Same idea, the diagram shows Active/Passive connections. I assume here I also want to create a trunk and in this case allowing either all VLANs on VLAN 101. Correct?
These three connections go to ports 4/6/8 on Core Switch 1 and 4/6/8 on Core Switch 2.
I was thinking about doing something like this on the core switches:
enable
configure
interface range te1/0/4, te1/0/6, te1/0/8
switchport mode trunk
switchport trunk allowed vlan all
On the stack (7 x 7048s) what do I do exactly? Same as above but using the ports on the modules? How do I specify them on the command line?
Routing is all done on some firewall for now so no Layer 3 used at all. That means the firewalls will simply have ports on all VLANs that need routing.
Crazy eh?
Thanks for ANY help guys. Appreciated!
