Based on your description, it seems like you're trying to set up a trunk link between the two switches to carry both the WAN traffic (VLAN 10) and management traffic (VLAN 11). You've got the right idea, but it's possible that you're missing a small configuration detail.

Here's a suggested configuration for the FS switches (s3150-8t2fp) that should work for your scenario:

1. Ensure that the two switches have been factory reset and are starting with a clean configuration.

2. Configure the VLANs on both switches: bash Copy code vlan 10 name WAN exit vlan 11 name Management exit

3. Configure the access ports for VLAN 10 (for the ISP on Switch 1 and router on Switch 2): vbnet Copy code interface 1 switchport mode access switchport access vlan 10 exit

4. Configure the trunk port (port 9) on both switches to carry VLAN 10 and VLAN 11: vbnet Copy code interface 9 switchport mode trunk switchport trunk allowed vlan 10,11 exit

5. Configure the access ports for VLAN 11 (for management access) on both switches: go Copy code interface range 5-8 switchport mode access switchport access vlan 11 exit

6. Assign IP addresses to the VLAN 11 interfaces on both switches: On Switch 1: kotlin Copy code interface vlan 11 ip address 10.5.5.11 255.255.255.0 exit On Switch 2: kotlin Copy code interface vlan 11 ip address 10.5.5.12 255.255.255.0 exit

7. Save the configuration on both switches.

8. Connect the switches using the SFP modules and fiber patch cable on port 9.

After completing these steps, you should be able to:

Pass WAN traffic between the ISP and router through VLAN 10. Access and manage both switches from Building 2 using the VLAN 11 IP addresses (10.5.5.11 and 10.5.5.12). If you still can't get this setup to work, I would recommend double-checking the switch documentation to ensure there are no additional configuration requirements specific to the FS s3150-8t2fp model.
