Bridging SFP+ Ports on a Zyxel USG Flex 700H






This FAQ explains how to bridge the two SFP+ ports on a Zyxel USG Flex 700H firewall to create a single, aggregated link.
# Background
The Zyxel USG Flex 700H features two SFP+ ports that operate independently by default. This setup might not be ideal for scenarios requiring a single, high-bandwidth connection. By bridging these ports, you can combine their bandwidth and utilize them as a single interface.
# Scenario
Let's say you need to connect your USG Flex 700H to a network switch or device that requires a high-bandwidth uplink exceeding the capacity of a single SFP+ port. Bridging the two SFP+ ports on your firewall provides the necessary bandwidth aggregation for this connection.
# How to Bridge SFP+ Ports on a Zyxel USG Flex 700H
Follow these steps to bridge the SFP+ ports on your USG Flex 700H:
1. Access the USG Flex 700H Web Interface:
Using a web browser, navigate to the web configuration interface of your USG Flex 700H firewall.
2. Configure Individual SFP+ Ports:
- Navigate to the interface configuration section.
- Configure SFP+ port 13 and 14 as individual interfaces.
Result:
3. Create a Bridge Interface:
- Navigate to the Bridge interface configuration section.
- Create a new bridge interface (e.g., bridge1).
- Now, assign the desired IP address and subnet mask to the newly created bridge interface. This IP address will be the single address used to communicate through the bridged SFP+ ports.
6. Save Configuration:
Apply the changes and save the configuration on your USG Flex 700H.
# Additional Information:
*Verification:
After completing the configuration, verify the bridge functionality by checking the interface status and testing network connectivity through the bridged interface.
