Configuring Fiber Port Penetration on Huawei Switches
To configure fiber ports on Huawei switches, you need to enable the interface, assign it to the correct VLAN, set the link type, and optionally apply port security and bandwidth controls.
Step 1: Access the Switch CLI
Connect to the Huawei switch via console, SSH, or Telnet. Enter system view mode to start configuration:
system-view
Step 2: Enable the Fiber Port
Identify the fiber interface (e.g., GigabitEthernet0/0/1 or XGE0/0/1) and activate it:
interface GigabitEthernet0/0/1undo shutdown
This command brings the port online and allows traffic to pass through .
Step 3: Configure VLAN and Link Type
Assign the port to the appropriate VLAN and set it as an access or trunk port:
port link-type accessport default vlan 10
For multiple ports, use the interface range command:
interface range GigabitEthernet0/0/1 to 0/0/10port link-type accessport default vlan 10
This ensures the fiber port communicates within the correct network segment .
Step 4: Apply Port Security (Optional but Recommended)
To prevent unauthorized access, enable MAC address binding and define protection actions:
port-security enableport-security mac-address stickyport-security max-mac-num 2
You can also configure protection actions such as shutdown, restrict, or protect to control how the switch responds to violations .
Step 5: Configure Bandwidth and QoS (Optional)
Limit outbound traffic to prevent congestion:
qos lr outbound cir 100000
Adjust the bandwidth value according to network requirements .
Step 6: Verify and Save Configuration
Check the port status and MAC table:
display interface GigabitEthernet0/0/1display mac-address
Finally, save the configuration to ensure it persists after a reboot:
save
Additional Considerations
- For XGE fiber interfaces, ensure the correct module is installed and the interface speed is negotiated properly using
auto speedcommands if needed . - Use
cable-snr-teston MultiGE interfaces to verify fiber cable quality, especially for high-speed links (≥2.5 Gbit/s), . - Always balance accessibility with security by applying ACLs to restrict traffic to trusted IP ranges. By following these steps, you can effectively configure fiber ports on Huawei switches, ensuring proper connectivity, security, and performance.
