I don't know why I am struggling with this, but here I am. I have inherited this project with no documentation and am being asked to make it work.
We have three remote sites on our radio network. All three remote sites are connected back to the main site via fiber on Cisco 3750 switches (hub/spoke). There will only be 2 devices connected to the ethernet ports at each site.
Device 1 IP address 10.100.100.1/24 Site 1 FA1/0/1, FA1/0/2
Device 2 IP address 10.100.100.2/24 Site 1 FA1/0/1, FA1/0/2
Device 3 IP address 10.100.100.3/24 Site 2 FA1/0/1, FA1/0/2
Device 4 IP address 10.100.100.4/24 Site 2 FA1/0/1, FA1/0/2
Device 5 IP address 10.100.100.5/24 Site 3 FA1/0/1, FA1/0/2
Device 6 IP address 10.100.100.6/24 Site 3 FA1/0/1, FA1/0/2
All switches have fiber connected on Gi1/0/1. They connected to the main sites switch on Gi1/0/1, Gi1/0/2. Gi1/0/3.
The questions I have are:
The ethernet switchports are configured for access mode. The fiber ports are configured for trunk mode. Is this correct? Or should the fiber ports be access as well?
The only vlan on the switch is vlan 1. Does the vlan 1 interface need an IP address? The devices have a gateway address of the main site switch. I don't know why there is a gateway address as this network is only interconnected with no outside connections (no internet, no other networks - it's a closed system).
This seems like it should be a simple config. But for the life of me I can't get it to work. What I really want are just "dumb" switches. How do I get these 3750s to act like that?
Any direction or assistance would be greatly appreciated.
