To add two MokerLink 2G08110GSM switches to your network (192.168.2.0/24) using 1 SFP+ port and a Direct Attach Copper (DAC) cable, follow these steps:

Overview of Your Setup

  • Current network: 192.168.2.0/24 (e.g., gateway at 192.168.2.1)
  • MokerLink 2G08110GSM: Managed switch, 8x 2.5G RJ45 + 2x 10G SFP+ ports
  • Interconnect method: 10Gbps DAC cable between SFP+ ports
  • Goal: Join both switches into your existing network with proper VLAN/trunking if needed

Step-by-Step Setup

1. Physically Connect the Switches

  • Plug the DAC cable between the SFP+ port 1 on Switch A and SFP+ port 1 on Switch B.
  • If connecting to a router or a main switch, use SFP+ port 2 from either switch to uplink.

2. Assign Management IPs

To avoid IP conflicts, give each switch a static IP in the 192.168.2.0/24 subnet.

  • Switch A:
    • IP: 192.168.2.10
    • Subnet: 255.255.255.0
    • Gateway: 192.168.2.1
  • Switch B:
    • IP: 192.168.2.11
    • Subnet: 255.255.255.0
    • Gateway: 192.168.2.1

You’ll do this from each switch’s web UI (default IP is usually 192.168.2.1 or 192.168.0.1).


3. Configure the SFP+ Uplink Ports

On both switches, configure the SFP+ ports as trunk or general mode depending on VLAN usage.

  • No VLANs: Set SFP+ port to Access Mode, VLAN 1 (default)
  • With VLANs:
    • Set SFP+ port to Trunk
    • Allow relevant VLANs (e.g., VLAN 1, 3, etc.)

Example on Switch A, SFP+ Port 1:

  • Mode: Trunk
  • Allowed VLANs: 1, 3

Do the same on Switch B, SFP+ Port 1.


4. (Optional) Enable VLANs

If you’re segmenting traffic:

  • Tag VLANs on trunk ports (SFP+)
  • Assign access ports to untagged VLANs (like VLAN 3 for IoT, etc.)
  • Use PVID for untagged ingress

Example:

PortModeVLANsPVID
1-8AccessVLAN 11
SFP+1Trunk1,3,101
SFP+2Trunk1,3,101

5. Test Connectivity

  • Plug a laptop into each switch and ensure they can both:
    • Ping the gateway (192.168.2.1)
    • Ping each other
  • Verify traffic passes between them over the SFP+ link

Tips

  • Use the same VLAN scheme on both switches if you’re trunking.
  • Secure the web UI (change default passwords).
  • Label ports in the UI for easy management later.

If you tell me what device is acting as your main router, and whether you’re running VLANs (like VLAN 3), I can tailor the trunk config or draw a topology diagram.

Great — with no VLANs, your setup is much simpler. Here’s how to add 2 MokerLink 2G08110GSM switches to your 192.168.2.0/24 network using the SFP+ ports and DAC cable, without VLANs:


What You Need

  • 1x DAC cable (SFP+ to SFP+)
  • Ethernet access to your router (192.168.2.1) or core switch
  • Web access to both MokerLink switches

     (192.168.2.10)              (192.168.2.11)

Configuration Steps

1. Physical Setup

  • Connect the DAC cable between the SFP+ port 1 of Switch A and SFP+ port 1 of Switch B.
  • Connect Switch A or B to your router (or main switch) via RJ45 (2.5G port) or SFP+ port 2 if available.

2. Initial Access

  • Plug a laptop into any RJ45 port on each switch.
  • Access their web GUI:
    • Default IP is often 192.168.2.1 or 192.168.0.1
    • Set a static IP on your laptop if needed to match that subnet.
  • Log in (check the manual for default login, often admin / admin).

3. Assign Static IPs

Assign management IPs that don’t conflict with your DHCP range.

  • Switch A:
    • IP: 192.168.2.10
    • Subnet: 255.255.255.0
    • Gateway: 192.168.2.1
  • Switch B:
    • IP: 192.168.2.11
    • Subnet: 255.255.255.0
    • Gateway: 192.168.2.1

Save and reboot if required.


4. Configure SFP+ Ports as Access Ports

Since there are no VLANs, set the SFP+ ports (used for interconnect) to Access mode with VLAN 1 (default).

On both switches:

  • Go to Port Configuration
  • For SFP+ port 1 (interconnect):
    • Mode: Access
    • VLAN: 1 (default)
    • Speed: Auto or 10G
    • Flow Control: Enabled (optional)

5. Confirm Link and Connectivity

  • Ensure both switches see the 10G link as UP.
  • Plug devices into either switch and test:
    • Can they get DHCP or ping 192.168.2.1?
    • Can they ping each other across switches?

Summary

  • DAC cable links the two switches at 10G using SFP+ port 1
  • One switch connects to your router (uplink)
  • No VLANs: all ports (including SFP+) are in default VLAN 1 / flat L2
  • Each switch gets its own static IP in 192.168.2.0/24 for management
